Description of the Issue

Same issue as #9510

Should have been fixed by f96d81a unless I misunderstand?

Unfortunately the commit did not fix the issue on win 7 at least.

In Notepad++ 7.9.2 I can do "Save as", file name: "lol" and "Save as type": "Normal text file (*.txt)" and the output file will be "lol.txt". Choosing the same options in 7.9.4 and the output file is named "lol" with no extension.

I don't have the option "Set Save dialog file extension filter to *.*" checked.

Steps to Reproduce the Issue

Edit for exact steps:
ALT -> F -> A -> this for for the "Save As..." menu, then I type my filename and hit Return.

The CTRL+ALT+S shortcut will also replicate the issue.
