How to fix Gtk.FileChooserDialogue height and resizing issues?
I am experiencing a strange phenomenon with the Gtk.FileChooserDialogue widget (Gtk3).
I can't get it to appear at the correct height. Output state height is 500px but its height is definitely much larger. Screen height is 1080px. This widget is almost reaching to the bottom of screen.
When manually resizing it with the mouse pointer, it uncontrollably shrunk to a very small size, get stuck to the top of the screen and I think it is just showing one of its child widget instead of the entire widget.
These issues are shown below. What am I doing wrong and how to fix them?
Running on Ubuntu 24.04.3. GNOME shell version is 46.

chooser.set_default_size(-1, 400)

Solution
On Linux Mint (based on Ubuntu 24.04) it remebers old size
and function run() uses it to change size.
I can get expected size when I set set_resizable(False)
but later I can't resize it manually so it is not so good solution.
I found that I can set size later assigning function to show
def on_show(self, *_):
self.resize(800, 500)
def __init__(self, title=None, parent=None):
# ... code ...
self.connect("show", self.on_show)
Later I found that this works for me only when I set both values.
When I use -1 then it doesn't work. resize(-1, 500).
I didn't check if -1 makes problem in other functions.
