Well, it takes creating a bunch of bug reports regarding file pickers:
- this aforementioned double onAccepted
- Accept button in multi picker instead of just accepting the selection takes up one level in the folder structure, it takes pressing it multiple times (depending on how deep you start) until you reach the top of the file system, only then it accepts selection and closes the picker
- if you feed a file picker dialog with default path, there’s absolutely no way to change the folder by the user
- no way to enter a file name for saving a new file,
- and probably more.
