Chromium workaround for CSS mask-image bug #7855

cee-chen · 2024-06-25T23:32:31Z

Summary

This bug was originally addressed in #6328 / #6343, but it turns out that it's affecting more components than just EuiModal (at least EuiFlyout as well - see elastic/kibana#180828). The browser-level bug in question is being tracked in https://issues.chromium.org/issues/40778541.

The amazing @kqualters-elastic helped us look into the issue and came up with an excellent workaround. Chromium appears to be not correctly applying a stacking context to mask-images with linear gradients and certain other children/properties. Using transform: translateZ(0) forces that stacking context and fixes the bug.

NOTE: will-change: transform and position: relative also works around the bug, but I deemed them to potentially have outsized side effects compared to translateZ.

Broken	Fixed

QA

Open Chrome or Edge and go to https://eui.elastic.co/pr_7855/#/layout/modal (bug does not affect Firefox or Safari)
Click the Show Modal button
Confirm the modal body content does not have a red overlay
Open your browser devtools and inspect .euiModalBody__overflow
Hide/uncheck the transform: translateZ(0) CSS and confirm that it does have a red overlay without the workaround CSS

might want to do the same on these lines in a scss mixin https://github.com/elastic/eui/blob/main/packages/eui/src/global_styling/mixins/_shadow.scss#L97-#L99

🚢 🐈‍⬛ Looks good to me! Thanks for digging into this. I can confirm it's fixed in Chrome and Edge 👍

- eventually going to be deprecated, but we can cross that bridge when we get to it

cee-chen · 2024-06-26T15:42:17Z

@kqualters-elastic Fantastic suggestion! I'll add that here as well, but as a heads up, we're looking to deprecate Sass mixins in the future as there isn't an easy way to keep them dynamic to theme changes/customizations compared to CSS-in-JS.

Hi Team,
we are also facing issue while expanding document from discover tab.
Will this fix work for below issue as well.

cee-chen · 2024-06-27T15:52:12Z

@asharma-5 It will, yes!

asharma-5 · 2024-06-28T03:19:21Z

@cee-chen Thanks for the response.
Getting this same issue in older releases (8.7.0, 8.8.2) too, are we going to backport to older releases?

cee-chen · 2024-06-28T19:42:42Z

@asharma-5 We can if requested, but we typically only do so if there's a specific Kibana team or customer requesting the fix. Please let us know if you would like to make that request!

asharma-5 · 2024-07-01T05:31:05Z

@cee-chen can you please provide the version of Kibana/elasticsearch in which this fix is released.

@asharma-5 Sorry for the delay in responding, I was out on PTO. The fix will be in Kibana v8.15.0+.

@cee-chen Thanks for the response, when 8.15.0 will be available ?

cee-chen · 2024-07-26T17:43:58Z

That I'm not sure about, sorry, I don't closely track Elastic's release schedule. It should be sometime soon however.

asharma-5 · 2024-08-06T06:53:26Z

@cee-chen Can you please check internally and provide an tentative date ?

cee-chen · 2024-08-06T15:53:01Z

I am not going to make that information publicly available before Elastic's official announcement, sorry!

Ah, it looks like Tomasz missed the feature freeze cutoff for 8.15 in elastic/kibana#187342 by a few days, and unfortunately the backport:skip label was added to the PR which prevented it from being automatically backported to the 8.15 branch. I'll manually kick off a backport here in a bit, and the fix will make it into Kibana v8.15.2.

Thank you for your patience on this @asharma-5. As a heads up, this bug only affects Chrome, so temporarily switching to the Firefox or Safari browser will resolve the issue.
