Proposal

Please re-state the problem

Split bill description having line breaks is not truncated in LHN

What is the root cause of the problem?

The root cause is that we are using styles.pre in OptionRowLHN.js:

App/src/components/LHNOptionsList/OptionRowLHN.js

Line 102 in 5ec2e8a

: [textStyle, styles.optionAlternateText, styles.pre, styles.textLabelSupporting],

This change was made in this PR: #27822
At the PR time, split bill description alternate text was broken (like it is now on prod) so it wasn't tested for it.

What changes should be made to fix this?

In the fore-mentioned PR, a similar problem was occurring and it was fixed by adding the ReportUtils.formatReportLastMessageText here:

App/src/libs/OptionsListUtils.js

Lines 379 to 380 in 5ec2e8a

	const properSchemaForModifiedExpenseMessage = ReportUtils.getModifiedExpenseMessage(lastReportAction);
	lastMessageTextFromReport = ReportUtils.formatReportLastMessageText(properSchemaForModifiedExpenseMessage, true);

So, we can follow a similar approach and change the MoneyRequestAction condition here:

App/src/libs/OptionsListUtils.js

Lines 366 to 367 in 5ec2e8a

	} else if (ReportActionUtils.isMoneyRequestAction(lastReportAction)) {
	lastMessageTextFromReport = ReportUtils.getReportPreviewMessage(report, lastReportAction, true);

to the following:

const properSchemaForMoneyRequestMessage = ReportUtils.getReportPreviewMessage(report, lastReportAction, true);
lastMessageTextFromReport = ReportUtils.formatReportLastMessageText(properSchemaForMoneyRequestMessage);

this would also match the backend which currently returns only the first line before the line break for the last message text

What alternate approach did you explore?

This is actually a big change in the whole approach of handling the formatting of lastMessageText.

Currently we are formatting the ReportUtils.formatReportLastMessageText() very randomly. While adding comments, we use this function to set the lastMessageText property on the report itself, but for things like Modified expense action we are using it in OptoinsListUtils.getLastMessageTextForReport to just display it in LHN.
Moreover, the backend also seems to perform formatting like removing the text after one line break.

What can be done is that all the logic for the line break formatting can be removed from backend as well as while creating optimistic reports and just keep it exclusively in OptionsUtils.getLastMessageTextForReport and apply the ReportUtils.formatReportLastMessageText for every message.

Additionally,
We can copy whatsApp by replacing every line break with whitespace in the ReportUtils.formatReportLastMessageText method by refactoring it like this:

function formatReportLastMessageText(lastMessageText,) {
    return String(lastMessageText).trim().replace(CONST.REGEX.LINE_BREAK, ' ').substring(0, CONST.REPORT.LAST_MESSAGE_TEXT_MAX_LENGTH).trim();
}

this would remove the need to have the "hacky" logic we use for modified expense currently:

App/src/libs/ReportUtils.js

Lines 927 to 932 in 5ec2e8a

	function formatReportLastMessageText(lastMessageText, isModifiedExpenseMessage = false) {
	if (isModifiedExpenseMessage) {
	return String(lastMessageText).trim().replace(CONST.REGEX.LINE_BREAK, '').trim();
	}
	return String(lastMessageText).trim().replace(CONST.REGEX.AFTER_FIRST_LINE_BREAK, '').substring(0, CONST.REPORT.LAST_MESSAGE_TEXT_MAX_LENGTH).trim();
	}
