Manual Tests

Change codeFance rule in /node_modules/expensify-common/dist/ExpensiMark.js to code below

             {
                name: 'codeFence',
                // ` is a backtick symbol we are matching on three of them before then after a new line character
                regex: /(?<![^^\r\n])(&#x60;&#x60;&#x60;(\r\n|\n))((?:\s*?(?!(?:\r\n|\n)?&#x60;&#x60;&#x60;(?!&#x60;))[\S])+\s*?(?:\r\n|\n))(&#x60;&#x60;&#x60;)/g,
                // We're using a function here to perform an additional replace on the content
                // inside the backticks because Android is not able to use <pre> tags and does
                // not respect whitespace characters at all like HTML does. We do not want to mess
                // with the new lines here since they need to be converted into <br>. And we don't
                // want to do this anywhere else since that would break HTML.
                // &nbsp; will create styling issues so use &#32;
                replacement: (_extras, _match, _g1, _g2, textWithinFences) => {
                    const group = textWithinFences.replace(/(?:(?![\n\r])\s)/g, '&#32;');
                    return `<pre>${group}</pre>`;
                },
                rawInputReplacement: (_extras, _match, _g1, newLineCharacter, textWithinFences) => {

The E2E test is failing because expensify-common changes are missing in the GitHub actions. Will create PR with required changes and then patch the library in Live Markdown
