Research direction
Investigate the `renderFromHTML` function in the Editor.js source, likely in the codex editor/src/components/modules/renderFromHTML.ts or similar. Look for the HTML to block conversion logic where inline elements like <strong> and <em> are currently ignored or stripped. Check if there is a parser configuration that maps these tags to editor.js inline formatting. The fix would involve adding support for these tags, possibly by extending the inline formatting definitions or modifying the HTML sanitization/parsing step. Review any existing tests for renderFromHTML to ensure new behavior is covered.
