Yes:

The file selection dialog appears. However, when a file is selected and the
selection is confirmed, "no file selected" remains. There doesn't seem to be
any communication about which file was selected. This is also how
“signal-desktop” behaves. The file dialog appears, but the selection does not
lead to any action after confirmation.
