fixed the issue #5348 and a typo

Fixed #5348 for windows by setting margins check for window decoration for DwmExtendFrameIntoClientArea instead and using value -1 margin for only the TITLE style

Keen on seeing this merged!

Thanks for diving in! Could you run through the various combinations of title and system backdrop styles and verify that they all work correctly and/or share some screenshots of these?
I think the change you're proposing sounds plausible, but I'd it's not immediately obviously from the diff which combinations should result in which outcomes, and I don't currently have time to dig into this myself on a Windows machine.

Thanks!

HI @wez , my bad , forgot to mention I did test before the pr and saw that only the TITLE decoration was having the issue where the acrylic was not being applied, and since TITLE by default has the windows buttons therefore it worked perfectly setting the margins for title to -1 while every other setting worked perfectly with these setting.
The Acrylic screenshots have the opacity set to 0.6 so the terminal looks as bit darker than the title bar
Essentially I have compared that all the settings looks exact same as without my change just without the bug
Tested on a Windows 11 machine
Adding the screenshots with my change as well

Thanks for confirming!
