Memory leak in Remote Desktop version 1.2.5559.0 (x64) and a few versions back

Question

Microsoft Remote Desktop has a memory leak.  This started a few versions back; I thought maybe it would be fixed in succeeding versions, but it has not.  You can watch with Task Manager and see it slowly consume more memory.  It starts out with about a 50MB footprint, but I've seen it at over 4GB before I had to kill it.  Right-clicking on the icon in the system tray did nothing (unresponsive).  So there is an issue somewhere.  I'm not sure what triggers the increase in memory utilization, as it seems to be stable at first.

Edition Windows 10 Pro Version 22H2

OS build 19045.4717

Experience Windows Feature Experience Pack 1000.19060.1000.0

UPDATE 8/18/2024:

Ok, I think I may have determined the genesis of this issue.  If the remote connection drops, Remote Desktop seems to start eating memory:

Here you can see it had consumed over 7 GB of memory!  The remote connection had dropped (evidently because the remote server was rebooted).

After closing the desktop app, the main process still remained, so I had to manually kill it via Task Manager:

Hello,

This issue may be caused by an application; consider capturing a user dump or a full dump for analysis.
