717858 - Using a XUL box with a max-height box in a dialog results in the XUL box having a minimum height

Status: NEW

(Core :: XUL, defect)

Description

[Jason Barnabe (np)]

Attachment: testcase

In a <dialog>, I have:

-A box with flex="1"
-A box with no flex, but with a max-height and overflow: auto. This box can have varying amount of content inside it.

My intention is that the second box is as small as possible to fit its content (and thus the first box is as big as possible given the size of the dialog), and that it will not grow taller than my specified maximum size, showing a scrollbar if needed.

When the dialog is taller than a certain size, everything's fine. Below a certain size, the first box refuses to get any smaller and the dialog's action buttons are cut off. Oddly, this does not happen inside a <window>.

See attached testcase. Resize your window to make it shorter.

Expected: red area shrinks all the way down to nothing as you make the window shorter
Actual: red area shrinks for a while, but then refuses to get smaller, causing the dialog's buttons to be cut off.
