Releasing Layer Mask issues, Window placement
Sorry—forgot to give you my system last time: Mac OS 10.12.6, AI 23.0.1
1) When I create a layer mask that includes clipping masks within, there are problems releasing the layer mask.
a) using the Layers panel Make/Release Button releases some of the clipping masks within. (see attached movie)
b) Using the Properties panel button and/or the Object> Mask> release will appear to do nothing, but is a redraw issue requiring View> Outline/View>Preview toggle.
2) when I startup Illustrator without the application frame it often misplaces my document so it's tucked behind the tools panel —sometime it is where it is supposed to be. I'll post a separate bug for that as well.
