Gutenberg-mobile: Copied content containing superscripts doesn't render correctly in the editor

[designsimply]

Describe the bug

After copying and pasting content from a Wikipedia page into a post, I found that the superscript values displayed as [SUP] in the editor instead of showing the actual content.

To Reproduce

1. Go to a Wikipedia page such as the Tiny house movement.
2. Copy any portion of the content containing superscripts.
3. In the app, go to My Sites > Posts > +.
4. Add a title and paste the content into the content area.
5. Preview the post.

Expected behavior

I expected that content with superscripts would display normally in the editor.

Screenshots

Smartphone (please complete the following information):

• Device: iPhone 11
• OS: iOS 13.4
• Version: WPiOS 14.5.0.1 TestFlight beta

This looks like a tag that it is not supported by Aztec.
To me it seems more like a feature request in this case 🤔

There's also a tinny difference in the HTML generated compared with Web:

On web:

<sup>
    <a href="https://en.wikipedia.org/wiki/Tiny_house_movement#cite_note-1">
        [1]
    </a>
</sup>

On iOS and Android:

<sup class="reference">
    <a href="https://en.wikipedia.org/wiki/Tiny_house_movement#cite_note-1">
        [1]
    </a>
</sup>

But Android is rendering it as expected.

I would ask @hypest about the priority of this.

Thanks! +1 for getting input on priority—I would vote medium or low unless it's a quick thing to fix.

Aside: I noticed that the same problem doesn't happen in the editor on Android.

^{Tested with WPAndroid 14.5-rc-2 on Pixel 3 Android 10.}

It does look like a medium-prio feature request, especially since based on what @etoledom mentioned the issue lies with Aztec (iOS) itself not currently supporting rendering. When Aztec-iOS supports it, it should be readily available in the block editor too. Can you move this ticket to the Aztec-iOS repo @designsimply ? Thanks!

In the meantime, if you want to tackle this @etoledom , feel free to 👍.

The sup and sub tags are now supported in Aztec iOS and by consequence they are also supported in Gutenberg mobile. Available since version 1.28
