What happened

On the canvas, when I press Ctrl+z, the last action is undone. If I then press Ctrl+z again, nothing happens.

When I perform more actions, Ctrl+z works again but again only once.

What you expected to happen

Another action is undone.

How to reproduce the problem

1. Perform two actions on the canvas (e.g. paint two separate stokes with the brush).
2. Press Ctrl+z. This undoes an action as expected.
3. Press Ctrl+z again. This does nothing.
4. Perform another two actions.
5. Press Ctrl+z. This undoes an action as expected.
6. Press Ctrl+z again. This does nothing.

Additional context

Older versions of Invoke are affected by this as well. I only noticed that this isn't intended behavior when I watched a studio sessions where seemingly unlimited amounts of undoing were possible.

In case it matters: I'm using Arch Linux with Wayland and KDE.
