Animation track keys shift position when selected

[TokageItLab]

I have investigated and found that the problem is probably due to the fact that InputEventMouseMotion at line 3049 in animation_track_editor.cpp is valid even though it should not be fired when closing a popup. But in animation_bezier_editor.cpp, mouse events are not fired when closing a popup although it is similar implementation with animation_track_editor.cpp. The timing of adding popups between them is different, so I tried changing the process priority of the popup node, but that did not solve the problem.

animation_track_editor.cpp: line 3049

if (mm.is_valid() && mm->get_button_mask().has_flag(MouseButtonMask::LEFT) && moving_selection_attempt) {
	if (!moving_selection) {
		moving_selection = true;
		emit_signal(SNAME("move_selection_begin"));
	}

	float moving_begin_time = ((moving_selection_mouse_begin_x - timeline->get_name_limit()) / timeline->get_zoom_scale()) + timeline->get_value();
	float new_time = ((mm->get_position().x - timeline->get_name_limit()) / timeline->get_zoom_scale()) + timeline->get_value();
	float delta = new_time - moving_begin_time;
	float snapped_time = editor->snap_time(moving_selection_pivot + delta);

	float offset = 0.0;
	if (abs(editor->get_moving_selection_offset()) > CMP_EPSILON || (snapped_time > moving_selection_pivot && delta > CMP_EPSILON) || (snapped_time < moving_selection_pivot && delta < -CMP_EPSILON)) {
		offset = snapped_time - moving_selection_pivot;
		moving_selection_effective = true;
	}

	emit_signal(SNAME("move_selection"), offset);
}

It seems that #92424 is causing the unintended firing of mouse events (I have confirmed that mouse events are not fired when the popup closes in prior commit from that), but I don't have a detailed reason as to why this is happening.

@bruvzg Do you have any idea?

Bisecting points to #92424 as the culprit:

Check if it's fixed by #93105, might be the same issue.

@bruvzg The issue still occurs in the latest commit after merging it, so it seems to be a different problem.

Seems like mouse move event can be received after closing popup wit
h a click and button can be still pressed, but I do not see anything wrong with it, since mouse is moving and button is pressed.

You can also do the same by opening a popup menu, holding down the left button (while hovering the menu separator) and closing the menu with ESC, the key will be moving until you release the button.
