Attachments: quoted multipart MIME message cluttered

Description Jiaxin Han 2020-06-09 09:10:37 UTC 
SUMMARY
When replying to certain messages the quoted texts cannot be displayed correctly in composer. After checking a few messages I find this is happening with multipart MIME message at least. Even though the composer displays the quoted message as a mess, if I still send the reply the received message can still be displayed properly.

STEPS TO REPRODUCE
1. click "reply" to a multipart message in MIME format


OBSERVED RESULT

the quoted message collapses to a single line and overlapping each other. completely not readable. See the red part in the attached screenshot.

EXPECTED RESULT

quoted message displayed properly.

Comment 2 Jiaxin Han 2020-06-10 08:57:38 UTC 
the quoted message is a long multipart mime message, which could be displayed correctly in plain text mode. when html display is enabled, the entire quoted message collapses to a single line of cluttered texts.
