Incorrect support data (ex. Chrome says "86" but support was added in "40")

Firefox

What did you expect to see?

Add note that dropdown options are not rendered vertically in vertical modes due to a browser bug(?)

Did you test this? If so, how?

On Firefox 109.0.1.

MDN metadata

Start with the css.properties.writing-mode entry referenced in the MDN URL and review the Firefox behavior described for <option> elements. Compare the Bugzilla report and the W3C writing-mode form results, then update the compatibility data to note that dropdown options are not rendered vertically in vertical modes and run the repository’s data validation checks.
