Real Time Drawing & Editing will not turn off for drawing shapes
When I have Real Time Drawing & Editing turned OFF, shapes (rectangle, ellipse) still show up filled while drawing, instead of just the vector outline as expected.
Steps to recreate:
turn off real-time drawing & editing
select random fill color
select shape tool
draw shape
expected result: only vector outline is seen during drawing
actual result: filled shape is seen during drawing
I tested this and found the same behavior on both my Windows 10 desktop and my Windows 11 Laptop, both running Illustrator 29.8.1 (64-bit).
There is no problem when moving an object, that still displays the vector outline as expected.

The team can reproduce it and intends to fix it
