Resizing will not trigger other viewDocument#mousedown events

Suggested merge commit message (convention)

Fix (widget): The resizing mechanism will not trigger other view.Document#mousedown events. Thanks to that while resizing an image inside a cell, the mouse will not trigger the table's actions. Closes #6755.

Unfortunatelly, there is some kind of weird issue (maybe due to changed priorities or maybe browsers just suck...)

On Chrome it sometimes doesn't work correctly - below are 3 tries - all have different result:

1. Failed to start (image dragged) resizing "works", no size feedback. Size saved.
2. Drag started, no size feedback. Size not saved.
3. Drag started (ignore the selection on other stuff), size feedback visible. Size saved.

On Firefox the most common scenario is "2".

If I set priority to 'normal' it backs to working normally AFAICS but the bug with table select gets back.

WHAT about switching priorities? I mean: low for events in TableMouse and normal (as it is on master) for resizing?

I feel like there's some bigger dpendency tree of those events which might behave differently in FF and Chrome and I don't have a clue why is that.

OTOH, I'd check this: #4600 if it could solve this problem (assuming revert to old Resizer events handling :( )

@jodator, could you check the PR once again?

LGTM 👍
