Issue description

The localization remaps menu is broken since this change, as can be seen in the screenshots below

Before, the two lists of entries are visible:

After, the lists are all squashed:

Unsure what specifically in this PR broke it, could be the change from VBoxContainer to MarginContainer

This effectively makes the remap editor unusable, the other localization editors seem to work correctly as they're not partitioned, went through the other editor interfaces changed in this PR and couldn't find any other regressions

Steps to reproduce

Open Project Settings > Localization > Remaps
