1694549 - Attachments bar gets pushed out of sight when message body height is much reduced, e.g. with small app window, large header, or showing all headers

Status: NEW

(Thunderbird :: Message Reader UI, defect)

Description

1. View a message with attachments
2. Select View --> Headers --> All in the main menu

Notice the attachment bar is invisible now. This depends on the TB window height.

Using daily at the time?

Comment 2

[Alessandro Castellani [:aleca]]

Does this still happen in daily or beta?

Comment 3

[Ping Chen [:rnons] (away)]

Still the same.

This depends on the TB window height.

It depends on the #messagepaneboxwrapper height, I can reproduce by dragging the top border to decrease the height. At first the #messagepanewrapper shrinks, when the height can only contain 5 or 6 lines of message body, further decreasing of height will make #attachmentView the attachment bar disappear.

I tried and I can also reproduce this in 91 without the "All headers" visible.
This is a XUL layout issue, most likely caused by the splitter and how they resize things.
This doesn't happen with the new about3Pane.

What do we want to do here?
It seems to be a somewhat of an edge case on a XUL element that we will remove in the next cycle.

Orthoganal to this issue ... Bug 923957 - Message window size too small - suggests adding a hint in the message preview header that attachments exist

This won't just cut off the attachment bar but also text at the bottom of the e-mail, making it worst case basically unreadable (or at least not all of it). So it'd be nice if there was some workaround. Or what's the sort of time frame for when this component is dropped entirely to address this?

114 is next year.

This seems to be even worse on 102, Thunderbird is now near unusable for me because the header area (From/To/Subject) is now even larger with "Headers" set to "Normal". So this bug isn't limited to "all headers" at all. At this rate I can't even fully see the e-mail text let alone the attachments. I'm not sure waiting for 114 is the best idea to solve this.

I'm not seeing this with 115.
Ellie, Jared do you agree?

Comment 12

[Ellie]

Still happening on 115, it just happens at smaller window sizes (and also instead of attachments, the content might now be out of sight and unreadable). This will only be solved if all areas including e-mail content area and attachment bar have a minimum height, and the entire vertical space gets a vertical scrollbar once it no longer fits. Alternatively, Thunderbird would need to have a different minimum window height but with Linux phones and all it might be more productive to try to fix this.

Attachment: Missing scrollbar as seen in Thunderbird 115 once area gets too small. Especially with large header area (the one in the video isn't so big), very possible that the content just isn't readable anymore

I was also able to reproduce this behavior.
