P: Add a Horizontal scroll bar in the Book Modulewhen enlarging a page 1:1 or 4:1 (Windows)

I just updated to the latest version of Lightroom 10.1.1 and I still have the same problem that I reported on July 2017!

I copy what I posted then since nothing has changed:
In book module the horizontal scrollbar is missing,  I can only scroll vertically.

The main problem I have is that if I select any  zoom ratio to check text properly,  I can only see (zoomed)  a stripe from top to bottom of  the page since I am not able to scroll horizontally.               It seems that the white square in the preview button gets stuck and the only movement that can be done is up and down.

I hope the screen shots help to make it clear ( Fit,  1:1,  4:1) Thank you for your help!

 4:1).

I submitted this same bug yesterday because while I searched for an existing issue I didn't see this; @Rikk thanks for linking to here. But 5+ years and no fix, probably not going to happen.

Workaround: Forget zoom. If you need to change something other than the spine of a book, just click all over the place until you happen to select what you want to change. Or use 50 pt text all the time so you don't need to zoom at all.
