Widgets: Fix custom HTML widget editor content not updating after save.

An integer comparison is performed against `control.currentErrorAnnotations`, but `control.currentErrorAnnotations` is actually an array. This fixes that comparison so the content saves correctly.

Props barryceelen.
Fixes #43657.
