Build 2023 crashes scanning the same file in multiple panes

Build 2023.
Show layout 2 (vertical double pane). Add a folder to the project.
Now open the same file in scan mode (single click) in both panes. That is, click one pane, single click the file, then click the other pane and single click the file.
Bizarre behavior results. For example, I'll drag the left pane scrollbar, and the right pane actually scrolls. Eventually, the app quits unexpectedly.
