test case

Version: 
  Safari 10.1.1 (12603.2.4)
  Safari Technology Preview, Release 33 (Safari 11.0, WebKit 12604.1.25.0.2)

Hardware: 
  MacBook Pro (Retina, 15-inch, Early 2013)

OS: 
  macOS 10.12.5

Redraw error when a list/combobox is updated. 
Bug produces in Safari 10.1.1 as well as Safari Technology Preview 33 (Safari 11.0, WebKit 12604.1.25.0.2)

1. Open the attached test case.
2. Tab to/click on the text field to bring it into focus. A listbox will be displayed beneath the text field.
3. Type 'ca' (or any other characters) into the text field to filter the results. Only 3 relevant results should remain in the dropdown list.

Notice that below the shortened dropdown list, there is a residual of box-shadow from the original list.

This will only be resolved when Safari window goes out of focus (switching to other applications, then back to Safari).

I am not able to reproduce any stuck box shadow in Safari 16.2, Safari Technology Preview 161 and it is moving box shadow similar to content in drop-down and matching with Chrome Canary 111 and Firefox Nightly 110.

Marking this as "RESOLVED CONFIGURATION CHANGED". Please reopen if it is still happening. Thanks!
