Feedback: All Apps Start menu does not scroll properly when folder is expanded

I would like to report a bug in the scrollbar handling for the All Apps list in the Start Menu. When you expand one or more folders in the All Apps list the scrollbar does not track the mouse properly.

Duplication steps:

In the Start Menu click All Apps

Scroll down to the Windows Accessories folder and click on it to expand it.

Now, using the mouse, click and hold on the scrollbar button then scroll back and forth to the top and bottom of the list.

The mouse does not stay on the scrollbar as you scroll. In order to scroll all the way to the top or the bottom. You have to release the mouse button and click and hold again to scroll all the way to either end.

Most likely this occurs because the scollbar maximum property is not properly set when folders are expanded.

 

scrolling bad

New event. When placing cursor over a list or row of columns, even the volume bar scrolling is automatic and proceeds to one end of the series and stops. The scrolling also stops when I move the cursor away from the list but am unable to select anything in the list. Not all the possible lists are effected. Other sites have recommended mouse/kb fixes. Have tried all those but the phenomena persists. Have not had any known updates recently and don't have a restore point to try. Any other suggestions? W10Pro 1903

 

Corrupt cortana not displaying properly

As per my below image, when I open cortana the display does not look right. There are three options under "can I be of assistance?" (or one of the other sayings things it puts there) which only become visible when I hover over them. I don't believe this is the proper behavior. Also in the "pick up where I left off" section it just oddly shows icons of the program I was using and doesn't give the name of the file. I don't believe this is the correct behavior either. Clicking on one of the icons opens up a recent file.

I tried following these steps with no luck - Reinstall and Re-register Cortana in Windows 10 | Windows 10 Tutorials

Any other suggestions are welcome.
