364135 - XUL boxes with overflow don't reflow when box properties are changed

Status: NEW

(Core :: XUL, defect)

Description

[Neil Deakin]

A box with overflow set to 'auto' or another value that is not 'visible', doesn't reflow when the orient, dir, etc is changed:

<box id="e" width="50" height="50" style="overflow: auto;">
  <button label="Item1"/>
  <checkbox label="Item2"/>
  <button label="Item3"/>
  <button label="Item4" minheight="120"/>
  <button label="Item5"/>
</box>
<button label="Broken" oncommand="this.previousSibling.orient = 'vertical'"/>

Expected: The contents of the box should be redisplayed vertically when the button is pressed.
Actual: Nothing happens

Works OK without the style attribute in the example.

Not a regression from the reflow branch though.
