Directory inconsistency when opening an editor FileDialog

When setting up a different default directory for new projects, I found the location at which the File Dialog opens is inconsistent. It doesnt remember where it was, and also gets the drive letter wrong.

In Godot 3.0.6

I open a project, I go to Editor Settings, and this is the current directory:

If I open the file dialog to set a new path, it opens in the same directory as my project, with correct drive letter:

If I navigate elsewhere and close the dialog, it remembers where it was if I open it again.

In Godot 3.1 alpha2

I open a project, go to Editor Settings, it starts out the same:

But, if I click on the directory icon to change it, it opens in the directory indicated by the property, which I guess was an intented change? If yes, that would also explain why the dialog no longer remember where it was when opening it again. But more importantly, you will also notice that the drive letter is wrong, which forces me to select C:, and then D: again to trigger the change and see the correct drive.

Also, if I write just D: in the address bar instead of using the dropdown, it doesn't just go to D:, but instead warps straight into my project folder (Which is in D:/some/where/in/a/folder). This did not happen in 3.0.6.

Is this still reproducible in the current master branch?

Still valid in 45d627a (although slightly different)

Selecting a drive opens root directory, unless it's the same drive as project, in which case project directory is opened.
