Can reproduce, but no need to block on this, I'll demote. Also going to update the price as it's most likely a simple change.

Proposal

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

Strikethrough line is white on links and emails

What is the root cause of that problem?

We already have text-decoration styles applied to a tag, so the styles from the del tag isn't applied correctly because the text-decoration-color: rgb(90, 176, 255);.

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

To apply both underline & line-through we need to wrap the TNodeChildrenRenderer with Text which will apply the styles for the line-through .

Steps:

1. Create a new HTML engine util function named isChildOfDel which will identify if the anchor is inside del tag or not.

function isChildOfDel(tnode: TNode): boolean {
    return isChildOfNode(tnode, (node) => node.domNode?.name !== undefined && node.domNode.name.toLowerCase() === 'del');
}

2. Check if the anchor is inside del tag or not.

const isInsideDel = HTMLEngineUtils.isChildOfDel(tnode);

3. Wrap the TNodeChildrenRenderer with Text with correct textDecorationLine style, we also need to flatten style from prop.const flattenStyles = StyleSheet.flatten(style as TextStyle);

<Text style={[flattenStyles, {textDecorationLine: isInsideDel ? 'line-through' : undefined}]}>
    <TNodeChildrenRenderer tnode={tnode} />
</Text>

Result

strikeThroughColor.mp4

Alternative

Or we can only show the line-through by overriding the styles if it is inside del .

style={[parentStyle, styles.textUnderlinePositionUnder, styles.textDecorationSkipInkNone, style, isInsideDel && {textDecorationLine: 'line-through'}]}

@francoisl, can you pls increase the bounty🙏🏻, this isn't a simple change, It took me good amount of time to figure out the root cause and to find a solution. Even if my solution is not valid then also I think we can't find a simple change.

[situchan]

@Krishna2323 this was deploy blocker. Are you able to find offending PR?
I suspect this came from expensify-common while working on live markdown regression fixes

[Krishna2323]

No, I couldn't find the offending PR.

Proposal

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

Strikethrough line is white on links and emails

What is the root cause of that problem?

regression from this line:
https://github.com/Expensify/App/pull/35462/files#diff-4935ec01feca8054d8a080f44501a37a1cf1398ffd19e0b46d3551a56e5ba313R66

- style={{...props.style, ...parentStyle, ...styles.textUnderlinePositionUnder, ...styles.textDecorationSkipInkNone}}
+ style={[parentStyle, styles.textUnderlinePositionUnder, styles.textDecorationSkipInkNone, style]}

So style overrides other custom styles by putting at the end

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

fix that order so put style at the beginning as before

style={[style, parentStyle, styles.textUnderlinePositionUnder, styles.textDecorationSkipInkNone]}

[Krishna2323]

I think we can't find a simple change

Lol 😂, I thought we need both, underline & strike-through at the same time.

[situchan]
