• Guteberg Mobile PR: Add support for the Mark HTML tag and updates Aztec iOS to 1.19.5 wordpress-mobile/gutenberg-mobile#4162
• WordPress iOS PR: Update WordPress Editor iOS to 1.19.5 wordpress-mobile/WordPress-iOS#17370

Description

Updates Aztec iOS to 1.19.5, with this and with the recently released Aztec Android, it adds support for the mark HTML tag.

How has this been tested?

• Open the app with metro running
• Toggle to HTML mode
• Paste the following snippet:

<!-- wp:paragraph -->
<p>Hey <mark style="background-color:#f0c25d;color:#ff0000" class="has-inline-color">there!</mark> this is a test.</p>
<!-- /wp:paragraph -->

• Toggle back to Visual mode
• Expect to see the text: Hey there! this is a test in the editor. It's expected to see the text color (not the background), and the customization for this new format is under development on mobile.
