Stroke aligned to Inside/Outside in Clipping mask Path object is disappear
When I create a clipping mask, I can set stroke color and size for Clipping mask path object and it works well. But I need to set stroke align of my Clipping mask from Center to Inside. Immediately when I change Stroke align to Inside (or Outsize) - it is disappear from object display.
How to reproduce this bug in Adobe Illustrator CC 2018:
Create Circle inside Rectangle as clipping mask
Select Clipping mask Path object (Rectangle) and apply any stroke to them (eg 1pt black) - it shows normally.
Change Stroke align to Inside or Outside - it will disappear!
Change back Stroke align to Center - it will return!
Why this happens and where is the source of this problem? Why Clipping mask stroke works only with Center aligned stroke?
How can I force Inside (Outside) stroke for clipping mask stroke? If this is Illustrator bug, maybe some workarounds exists?

Me too! I hope they answer this question. I also can't use the strokes in the Appearance tab on a clipping mask...
