Using mouse click + drag to change values in inspector numeric properties teleports mouse to top left of screen

[EricEzaM]

Godot version:
master 78861fd

OS/device including version:
WIN 10

Issue description:
As title

Steps to reproduce:
Click and drag on a number property in the inspector - your mouse disappears. When you let go, your mouse appears in the top left corner of the Godot window (position 0,0)

Note if you do the same thing on a property which has a slider bar (e.g. the rotation in the below gif) the mouse is not teleported, but still disappears.

When the mouse is released, the mouse position is warped to grabbing_spinner_mouse_pos, but this value is only updated when the spinner is visible, as shown below:

godot/editor/editor_spin_slider.cpp

Lines 271 to 285 in 4828667

	} else if (!hide_slider) {
	int grabber_w = 4 * EDSCALE;
	int width = get_size().width - sb->get_minimum_size().width - grabber_w;
	int ofs = sb->get_offset().x;
	int svofs = (get_size().height + vofs) / 2 - 1;
	Color c = fc;
	c.a = 0.2;
	draw_rect(Rect2(ofs, svofs + 1, width, 2 * EDSCALE), c);
	int gofs = get_as_ratio() * width;
	c.a = 0.9;
	Rect2 grabber_rect = Rect2(ofs + gofs, svofs + 1, grabber_w, 2 * EDSCALE);
	draw_rect(grabber_rect, c);
	grabbing_spinner_mouse_pos = get_global_position() + grabber_rect.position + grabber_rect.size * 0.5;

The value also needs to be updated when the slider is hidden.

Marking as Junior Job, as I think it might be a reasonably simple fix. If you want to try solve this but have questions hit me up.

This might be regression from #48444
I moved the variable update, but maybe it should update in both places...
