In order to reproduce the bug do: [1] Start LibreOffice and open new text document. [2] Right click on of the toolbars. The context menu is displayed. [3] Chose “Close Toolbar”. Nothing happens, context menu is still displayed. Expected: Toolbar and context menu are closed. With version 5.0.3 the toolbar is closed, hence regression.
This sounds like bug 95341. Setting setting status RESO DUP. *** This bug has been marked as a duplicate of bug 95341 ***
