Issue Summary

After invoking the Navigation tools using modifier keys when using any drawing tool the HAND tool icon gets locked and won't be removed even when drawing.

Workaround: The icon can only be reset by changing selecting the active tool either by pressing the keyboard shortcut or clicking on the toolbar icon.

This was tested with all the cursor options turned OFF, that is having only the "default" crosshair cursor. It happens when the "Tool cursors" option is turned ON as well.

It seems to only happen with a stylus / tablet. It doesn't occur with mouse input.
It also happens only when zooming in / out, not with panning the canvas nor tilting.

Expected Results

Despite this bug being non-critical, the icons should never lock when invoking the navigation tools via modifiers or otherwise.

Steps to reproduce

1. Select a drawing tool
2. Press CTRL + Click & Drag to zoom in/out using the RMB only (MMB is buggy but doesn't cause this behavior for me, but you're welcome to test either way)
3. Notice the Hand cursor is locked and replaced the current tool / crosshair cursor.
4. Try drawing and notice that the icon is still locked.
5. Select a the same tool via shortcut or toolbox, the icon resets.
