In Blockbench 5.0, UV cannot be rotated in Per-Face UV mode on a GeckoLib model. #778
Description
In Blockbench 5.0, when using the GeckoLib Models and Animations plugin and editing a GeckoLib animated model with Per-Face UV, the slider to change a UV face's rotation is missing.
When added to the toolbar manually it still does not appear. It is greyed out, with the text under stating "Some tools might be hidden because they are not available in the current mode, format, or situation."
Models which had faces rotated like this still have the rotation applied, so it would seem the format still supports UV rotation, but is communicating to Blockbench that it does not, or not communicating that it does.
