Capture Column Widths in Table/Matrix Visuals as part of Bookmark Exploration State

Would be helpful if we could use bookmarks to adjust column header widths in a visual.

Currently, that information does not seem to be captured, even when using "Personalize Visuals" with the "Auto-size width" option turned off.

This would be very helpful because users need to readjust the columns every time they open a bookmark
