In-Editor Render Preview Stuck

Background Info: When outside the filter editor, we are allowed to switch between a smaller preview size and the full render size.

The Problem: When inside the filter editor, this preview/full size is "locked" or "stuck" without a way to switch.

If I make a new image while in the editor (a feature I like ) it doesn't fix the problem, and remains the percentage smaller that the old image preview was at.

For example I tried making a new 600x600 image and it remained about 150x150 because the last larger image had been sub-sampled for the preview size.

Leaving the editor and making a new image or switching between preview-size toggle is the only workaround.
