button's tooltip does not hide if click on the button results showing dialog covering the button

[vbatishchev]

Button with bind tooltip and onclick function which shows a dialog. Hover mouse pointer over the button. Tooltip appears. Click on the button. Tooltip disappears and dialog appears. The dialog covers the button. To close the dialog move mouse pointer to right corner of the dialog and click on cancel cross. Dialog disappears. The button visible again. Button's tooltip appears. Mouse pointer not on the button anymore. Also scrolling the form with wheel results detaching the tooltip from the bind item. This is annoying bit. Every time user opens and closes daughter dialog random tooltip appears on the form. Random because mouse pointer is not on the element binds to the tooltip and the user can scroll the form making the tooltip detached from the item. To hide the tooltip user must click somewhere on the form.

As an extension of the bug move focus to the button with bind tooltip with tab key on the keyboard. Tooltip appears. Scroll the form with wheel on the mouse. The tooltip on the form stays still while form with the button moves. The tooltip is visually detached from the button it bind to.

I believe this is fixed by #8267, for 1.10. If you attach a test case I'll try it to confirm.

About the scrolling, that's a separate issue, but it's also already covered, by #15388.
