Refreshing app displays raw html without style for a while

[kboul]

Not sure whether this is a bug, but anyways I would like to listen to your opinion.

In the last couple of days after upgrading handlebars due to a security vulnerability (not sure if this is coincidental or not) if I hit the refresh button either on Chrome Version 70.0.3538.77 (Official Build) (64-bit)
or in Mozilla Firefox 65.0.1 using Ubuntu 18.04.2 LTS I am able to see for a second, for a blink of an eye the raw html of the page I am landing without the styles implemented in development mode. I tested in production after building the app and everything is ok there.

I am using sass ("node-sass": "^4.11.0") in my application if that makes any difference.

I tested with a newly created create-react-app and the same applies there. Specifically, if you hit refresh button on the browser you are able to see "Edit src/App.js and save to reload." and "learn React" in raw html on the top left corner on the screen for a second before style is applied instantly.

I can provide my package.json if it is necessary for my create-react-app.
Is this an expected behavior because I can assure you that before I did not notice something like this or is this something that is applied on my local machine due to a misconfiguration?

index.html is almost the same as in the boilerplate. Only have added this line of code
<link type="text/css" rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700">

I also forgot to mention that I am using absolute paths in my application while having declared
NODE_PATH=src/ on .env and that recentry upgraded to node v11.10.0 with npm v. 6.8.0
I downgraded to node v 10.15.2 but that did not fix the issue.

Thank you in advance.

Hi @kboul!

Pretty sure that this is duplicate of #6399 and should be fixed in 2.1.6. when it comes out. Meanwhile you can try downgrading to [email protected]. Note that the issue should only affect development builds, not production builds.

Thank you very much sir. That allows me to breathe normally again for now as I was very anxious :)
