keyboard shortcut for Save for Web no longer live updating

I updated to PS 27.7 and I noticed that in the Save for Web the Quality Preview no longer auto-updates when changing the value (w/o clicking on another field). In previous versions that was very helpful to zoom in a bit and see at what level of quality the images gets significantly worse. I could simply SHIFT+(up/down) to update in increments of 10 and (up/down) for single increment steps. Now I have to click or tab into another field for the preview to occur. This has nerfed my keyboard workflow!! (EDIT: Im asking about the quality adjust W/O clicking tabbing into another field!) What used to be simple is now slower than typing all this... :( (I now have to adjust, tab out, see the preview, tab back with shift, adjust, preview, but I can no longer do quick comparisons!). Any idea if that can be 'reverted back' somehow? Other suggestions?
