Create Issue

---

1. Add "webview.experimental.useIframes": true to the settings file.
2. Create a markdown file, or open an existing markdown file.
3. Run the "Markdown: Open Preview to the Side" command.
4. Press Ctrl+F to reveal the find widget, and try searching in the iframe.

Some things to try for step 4:

• How well does searching work with an IME?
• How well does searching work with a screenreader/a11y tool?
• Are there any issues if one tries to change the markdown file content, or close and re-open the markdown preview while a find session is in place?
• Does reloading during a find session cause an issue?

Hey @jrieken - I finished up my testing and checked off my name / assignment yesterday. Is it safe to check off yours and close out this issue too? Or was there a reason you assigned it back to me? Thanks!

Yeah, forgot my checkbox here...
