# If you make a container-based UI inside a WindowDialog, there is a chance it will overflow
# because WindowDialogs don't adjust by themselves. This happens when the user has a different
# font size than yours, and can cause controls to be unusable (like buttons at the bottom).
# This script adjusts the size of the parent WindowDialog based on the first Container it finds
# when the node becomes visible.
