### Describe the Bug

Microsoft Edge on iOS and other devices might need some customization - maybe the permission management is different, so we'll need to adjust that

### Expected Behavior

It's syncing just fine

### To Reproduce

I just can't select a directory when configuring it

### Debug log provided

- [ ] I have provided a debug log file

No files or tests are named. Start by reproducing WebDAV configuration in floccus 5.8.6 on Edge for iOS, focusing on the directory-selection step and comparing its permission behavior with supported browsers. Done means selecting a directory successfully and confirming bookmark syncing works.
