Steps to reproduce
- Open composition.
- Make sure the window is relatively small.
- Add lots of attachments.
If the attachment area becomes larger than the available vertical space, the window's content height will become cropped at the bottom. This means that the status bar disappears, and later attachments cannot be seen.
The user can fix this by using the splitter between the attachment area and the message editor to lower the height of the attachment (it might take a few steps). Note, that this solution would not be available to a keyboard user.
Or they could increase the window size, but this is usually limited by the screen height. Or they can collapse the attachment pane, but once it opens they will have the same problem and they cannot see the last attachments.
We stop the attachment area growing beyond the available space in the window.
This happens because we set the
height of the attachment area directly when we add attachments.
