Steps to reproduce:
- Open Library in a tab or floating window, and put it in Grid View.
- [I'm assuming the default column heading order ([Cover icon], Type, Title, Author, ...); doesn't matter, but just note that my instructions below assume Author is the column immediately to right of Title]]
- [If necessary] Shrink width of Library window or show enough columns that horizontal scrolling is necessary to see all the columns.
- Scroll horizontally to the right just enough to have the Title column halfway visible.
- Try to drag the Author column heading to the left side of the Title heading.
Expect: window to scroll left horizontally as you drag past the left edge of the window, so that you can see where to drop the Author heading. But it doesn't scroll.
This is not such a big deal in a case like this when columns are near each other and I could have just as easily NOT scrolled to the right first. But if I'm trying to move one of the columns that is way far to the right (by default) over to the left, that is not possible without scrolling, and so I can't do it unless I make all the columns narrower first, then drag to reposition, then resize the columns. Or drag it over in stages, first to the left of the immediately adjacent column, then over a bit more, etc., until I get it to where I want it. Not ideal.
