Bug: Layer selection visual indicator doesn't update after selecting with shift

[Lukas]

Layer selection often shows selection wrong.

Steps to reproduce:

1. Create a project with 5 layers
2. Make sure you have no layers selected (of course the current layer will be highlighted, this doesn't matter)
2. Hold Shift and click the thumbnail of the top layer to select it
3. Keep holding Shift and click the bottom layer to select all layers

Now it will show a selection border around the thumbnail of the top and bottom layer, but actually all layers are selected. The UI just doesn't update to show it correctly. It should have updated after step 3.

4. Run a button that just runs "Command: tv_warn" to force the UI to update

Now it will show the selection properly.



Slightly related bug:
Layer: Go Up with Selection & Layer: Go Down with Selection
But these shortcuts will always throw away your current selection and select the last two layers only. It makes them pretty useless. You'd expect going up with selection twice will select three layers, not 2.

Confirmed on my end, thanks!
