Sure. I've identified an issue on the master branch where, if the cursor is
not inside the table at WS,  `org-table-begin' in
`org-table-header-set-header'
gets the beginning position of the next table in the buffer.
so `(pos-visible-in-window-p beg)' returns true, causing the header overlay
of the table at WS to not display.

Moving point to WS ensures`org-table-begin' to get the beginning position
of the table at WS, regardless of the cursor position, resolves the
above problem.
