IOS notes app – drawing tools disappear when using Pencil

apple-penciliosipadnotes.app

I noticed the following behaviour and consider it a bug. How to proceed?

When I open a new note in the iOS notes app (ipad pro 2020) and I open
the drawing tools [1] and I start to draw with the Pencil then the
drawing tools stay open (as expected).

When I close the drawing tools [2] and reopen them [1] and I continue drawing with the Pencil then the drawing tools minimise as if the "Auto-minimise" option was active (but it is
not).

This prevents e.g. the usage of the ruler tool (it disapears with the drawing tools).

Any idea how to appproach this? Can I file a bug report to Apple? Worth it?

An update to iOS 13.5.1 seemed to fix the issue. I got the hint in the Apple Discussion forums https://discussions.apple.com/thread/251558519?answerId=253012468022&page=1
