Bug 1447775 - Change persist mode immediately after sizemodechange change, r?jimm
|
||
|
|
|
||
|
|
Recently the window sizemode attribute is updated with 500ms delay (on Linux). It causes race condition
|
||
|
|
between reflow/CSS rule and window resize callbacks and also causes visual glitch when toolbar dragspace
|
||
|
|
is enabled.
|
||
|
|
|
||
|
|
TabsToolbar height is used at resize callback to do dragspace calculation. It has old values here
|
||
|
|
because it depends on 'window[sizemode="normal"] #TabsToolbar' css rule which is applied with 500ms delay.
|
||
|
|
|
||
|
|
So we use old TabsToolbar height for the dragspace, then the sizemode us updated by PersistenceTimer and
|
||
|
|
a new TabsToolbar height is calculated but the dragspace size stays as we're not notified
|
||
|
|
about the TabsToolbar height update.
