Modal dialog closes when mouse button is pressed over the dialog window but released outside the window

Bug description:

STR:

1. Hover over the modal dialog
2. Press left mouse button down
3. Move mouse outside the modal window
4. Release the button

ER: Modal dialog is closed

AR: Modal dialog should not be closed since click actually occurred on the dialog. Closing of the dialog especially annoying when selecting a text on the dialog and accidentally move the mouse outside of the dialog. video.zip

Clarification: This is clearly a bug. I want a dialog to close on backdrop click (so I don't want to use static), but I don't want it to close when click is initiated on a dialog (for example, during text selection as shown in the attached video).

There is a simple fix for that issue and I have created a pull request. video.zip
