Disable Masters don't remove unused axis (with ital axis)

1

It seems that Disable Masters no longer removes an axis if all remaining masters share the same value for that axis. (3238)

For example, if all Italic masters are disabled, the ital axis remains in exported VF.

EDIT : It work with slnt axis, but not with ital

2

the ital axis is special. It will be added in a few places by default.

Could it be hidden in this case, to not appear in UI ?
