Move the mouse cursor on the dashboard over the maximize icon.
Wait till the "Maximize" mouse title appears.
Than click on the icon.
=> The widget opens in a maximized mode
But the black "Maximize" mouse title sicks to the cursor and will not disappear.
mouse title disappears after leaving the icon, also when the widget maximized
mouse title does NOT disappear
Hi @mathContao. Thanks for creating this issue. I was able to reproduce that on our demo using Firefox. In Chrome it seems to work fine. Guess we need to force closing the tooltips when the maximize button is clicked.
