Issue Summary

When inserting Bidirectional Unicode characters (e.g. U+202A) into RTE from virtual keyboard they are not escaped properly.

They are escaped when the text containing such characters is pasted. After saving the edited text it is rendered correctly regardless of how the text was inserted.

This does not affect 8.20.1.

Steps to Reproduce

1. Ensure the RTE is enabled in Jira.
2. Open Create Issue view.
3. Add code or preformatted panel into description.
4. Open your virtual input method (i.e. ctrl-cmd-space on Mac, on other OSes it may differ).
5. Insert some BiDi characters into the created panel.

Expected Results

The characters are escaped properly.

Actual Results

The characters are not escaped.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
