[Tableselection](  https://ckeditor.com/cke4/addon/tableselection) Merging cells

open status of their associated pop-up menus in the browser's accessibility
tree. * [#5022](  https://github.com/ckeditor/ckeditor4/issues/5022): Fixed: [Find

s/ckeditor4/latest/api/CKEDITOR.html#method-inline), [`CKEDITOR.appendTo`](https

cationTitle`](  https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.htm

the editor's application region label. This option, combined with [`config.title
`](  https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-

/CKEDITOR_plugins_clipboard.html#method-addFileMatcher) function allowing to
define file formats supported by the
[clipboard](  https://ckeditor.com/cke4/addon/clipboard) plugin. Trying to paste

function to correctly handle caching of CSS files. Other changes: *
