Description Wenson Hsieh 2022-05-22 16:16:03 PDT 
Specific repro steps in Mail, on macOS:

1. Set system language to an RTL language, such as Hebrew or Arabic.
2. Switch to an LTR input language/locale, such as en_US.
3. Reply to an email with LTR content.
4. Set the selection inside the quoted content, and hit enter to break apart the blockquote.
5. Type anything (e.g., "hello")

Expected: the text inserted in step 5 should be LTR.
Observed: the text inserted in step 5 is RTL.
