// Add two buttons to update emoji font size
<Button

  onPress={() =>
    setMarkdownStyle({
      emoji: {
        fontSize: 27,
      },

Reviewing the PR

[tomekzaw]

@VickyStash Could you please merge main?

[tomekzaw]

@VickyStash Also, it looks like the change has been extracted from #356, was that intentional? Do you think we should merge your PR first and then follow with #356 or we should merge just #356?

[VickyStash]

@tomekzaw I'm okay to merge the #356 only and close this PR.
I've tried to confirm it the issue comment. I had some doubts why the #356 was open from May.

[tomekzaw]

@VickyStash Thanks for your response. So it looks like your PR along with changes from #474 indeed fixes the emoji font size issue on RN 0.75. However, there's still a problem when updating text font size:

If you're okay with closing this PR in favor of #356 then let's do that.

Thanks again for your investigation – Expensify/App#47547 (comment) is the best summary of what happened here.

Closed in favor of #356

[tomekzaw]

Actually we've found one regression in #356 (comment) so we can't merge #356 in its current form.

Luckily, this regression doesn't happen on #475 (this PR):

Screen.Recording.2024-09-12.at.12.00.16.mov

So let's merge this PR as it fixes emoji.fontSize issue and does not break text suggestions.
