In GXT 3.0.2b, menu is getting detached from the button when page is scrolled.
In GXT 3.0.2b, when user clicks on the button to open a menu and then scrolls the page vertically, the opened menu is getting detached from the button - the button is scrolled up but the menu stays at the same place.
The same problem is observed in the Sencha GXT demo, Advanced ToolBar example - if you open the Paste menu in the Standard panel and then scroll the page, the menu will get detached.
Would it be possible to fix this problem for the next release?
I'm marking this as closed for now, as it does seem to already be fixed in an existing release - if you can reproduce this with 3.0.3 or newer, please let us know with a test case and we'll reopen and look into this.
