Proposal

Please re-state the problem that we are trying to solve in this issue.

Double strike-through is seen on emoji.

What is the root cause of that problem?

We previously prevented the emoji from being formatted in #40617. The strikethrough style is applied from the parent (<del>) and the emoji itself. In that PR, we apply an inline-flex style so the emoji won't be affected by the parent strikethrough style.

But in #47547, we changed it to inline because selecting the text with emoji won't have the same height.

Compared to when using inline.

What changes do you think we should make in order to solve the problem?

I think it's more important to prevent the emoji from being formatted compared to making sure the selection height to be same and it's barely noticeable too, so I suggest to use inline-flex back and add `textDecorationLine: 'none' to override the text decoration style on the emoji itself.

App/src/styles/utils/emojiDefaultStyles/index.ts

Lines 6 to 9 in e94df0f

	const emojiDefaultStyles: EmojiDefaultStyles = {
	...FontUtils.fontFamily.platform.EXP_NEUE,
	...display.dInline,
	};

const emojiDefaultStyles: EmojiDefaultStyles = {
    ...FontUtils.fontFamily.platform.EXP_NEUE,
    ...display.dInlineFlex,
    textDecorationLine: 'none',
};

What specific scenarios should we cover in automated tests to prevent reintroducing this issue in the future?

@bernhardoj Do we have any other solution to this problem?

[parasharrajat]

This looks like a duplicate issue of #14676.

[bernhardoj]

It was solved months ago, but it happens again.

[bfitzexpensify]

I agree that this is a duplicate of #14676

[bernhardoj]

@bfitzexpensify I wouldn't say it's a dupe because that issue is solved months ago, but this issue happens again, so we should fix it again.

[parasharrajat]

I agree with you but Expensify/react-native-live-markdown#591 is solving this issue at lib level.

[bernhardoj]

It's not a live markdown issue.
