Backslash disappears in Snapshot Prefix field

[dcflachs]

I have found that i prefer the format 2023-06-13T18-18 for naming my btrfs snapshots. The format string that creates this timestamp format seems to be {Y-m-d\TH-i}. A path of the form /mnt/snapshots/.appdata/{Y-m-d\TH-i} seems to work to create the desired snapshot when typed in the create snapshot dialog. The same path can also be saved in the Snapshot Prefix box on the Edit settings screen.

The problem is that when clicking the create snapshot button for a subvolume with saved prefix with the desired prefix the popup form is missing the backslash in prefix. /mnt/ssd-cache/snapshots/.appdata/{Y-m-dTH-i}

To reproduce save a snapshot prefix with the form {Y-m-d\TH-i} and then attempt to create a snapshot with it.
