SSMS 17 Bug: Can't copy from dialog popups: Unsaved documents cannot be cut or copied to the clipboard from the Miscellaneous Files project

There's a bug in the current 'separate installer' version of SSMS (2016 onwards)

It doesn't allow copy pasting from some dialog popups. Noticed it in the find & search/replace dialog.

I use this feature extensively to refactor code/deploy from template files

Never seen any other windows app that doesn't allow copying/cutting from a textbox

repro:
Bring up the search replace dialog (ctrl+h)
type some random text into the "Find what" text box
highight it (ctrl+a)
cut it (ctrl+x)

result: error message - Unsaved documents cannot be cut or copied to the clipboard from the Miscellaneous Files project. You must save the unsaved document(s) before cutting or copying them.
