Backport of #43693

Cherry-picked for 3.4.1.

I just tested this in Godot 3.4.1 rc1 and it does not work as I would expect.

Even if the whole scene tree is paused, including the control, the tool tip still shows up. I would expect the tooltip to only show up on the Control nodes which are processed (pause mode: Process), or inherit the pause mode from a processing Node (pause mode: Inherit).

However currently the tooltip shows up regardless of any pause setting.
This gives the user the same lack of control as hiding all tooltips by default.

Imagine you have a pause menu and you spawn it on top of your game with your game UI. The game and it's UI should be paused, but the pause menu should be processed. With this current implementation, the tooltips of the game UI would still show up. Even though all the user only would want the processed Controls to have tooltips.

Another issue I just noticed is how the tooltips appear at some offset location if there is a translated Camera2D in the scene. Not sure if this is a new issue or not since it is the first time I notice it:

tooltip_offset.mp4

I also just noticed the Control mouse filter "pass" has no effect on the tooltip. It will behaves identical to "stop".
"Stop" and "Ignore" behave exactly like you would expect: The top Control nodes tooltip shows up everwhere if it has "stop" mouse filter, and it does not show up if mouse filter is set to "ignore".
However "pass" just mimics "spot" behaviour, while I would expect the tooltip from the Control below to show up when the top Control has the "pass" mouse filter and I hover with my mouse over both. If the top has "pass" mouse filter, it should only show up in the region where there is no other Control tooltip below it. And in regions where there is a Control with tooltip below it, either both tooltips should show up or just the bottom one. However as it currently is "pass" has no purpose (possible similarities to #54529 ?)

Control Tooltip with mouse filter "pass" behaves like mouse filter "stop":

I can open up new bug issues for these, if desired.

You can open an issue about tooltip pause. For pass/stop too if there isn't one already. The camera bug is fixed in 4.0 (#11732)
