New commits: commit bf15445b7102a4e2bea2f96891093bc4bf07c4c6 Author: Michael Weghorn <m.wegh...@posteo.de> AuthorDate: Wed Aug 23 17:46:37 2023 +0200 Commit: Michael Weghorn <m.wegh...@posteo.de> CommitDate: Wed Aug 23 22:21:59 2023 +0200 tdf#99609 tdf#156473 a11y: Check whether row header exists Don't allow using `BBINDEX_ROWHEADERBAR` as the child index unconditionally, but only if the browse box actually has a row header. An `AccessibleTabListBox` doesn't have a header and instead returns the table when requesting the child at index 1 (`BBINDEX_ROWHEADERBAR`). Now that row headers are propagated to the Windows platform accessibility layer with commit 2b30d37bd555188733a006e1a5796461ab11d326 Date: Thu Aug 3 15:48:48 2023 +0100 tdf#156473 wina11y: Fix invalid write due to row/col mismatch in place, NVDA confusingly started announcing all cells in the currently selected row as row headers for the currently selected cell in the Expert Configuration dialog, because of the table being returned without this change in place (while the cells in that table don't actually have any row headers).
