Bug: Images Inserted From WP Media Library Do Not Contain Already Added Alt Text

[kelasante]

Expected behavior

When using the desktop browser, the alt text is automatically added in when an image inserted from the media library contains the alt text. However, this does not happen when using the iOS app.

Actual behavior

When using the Image block, images inserted via the media library do not automatically add in the alt text.

Steps to reproduce the behavior

1. Go to the WordPress iOS app and an image to the Media library with alt text.
2. Add an image block and insert the image.
3. The image does not automatically carry over the alt text from the media library.

Context

A visually impaired user, 28916050-hc, has to add alt text manually each time they insert an image from the media library into a block even if alt text has been added already.

Tested on iPhone 6 Plus, iOS 14.4.2, WPiOS 17.0

I've investigated this issue and have some info to add. The issue is happening when the Media object from WPiOS is being converted to a Gutenberg MediaInfo object; the MediaInfo object does not have an alt property

Below is a screenshot of where this is occurring in class GutenbergMediaInserterHelper

I transferred this issue to the gutenberg-mobile repository as the bug relates to the block editor and impacts both iOS and Android.
