Context menu does not work when select all is used

Version: 4.18.0

I noticed that if you use "Ctrl+A" to select all
if you then use right mouse button on the selected items to open up context menu to be applied to all of the items, it then de-selects all the items and just ends up selecting just the item that the RMB was clicked on.

If you instead select all of the items manually, by clicking on top file and then hold shift and click on the bottom file, then this issue does not occur. It seems to only happen with the use of the "Select All" "Ctrl+A" shortcut.

Thank You
