Clicking on a down-arrow next to Font Color and Background Color toolbuttons opens a popup windows with color grid and some other buttons. However when you try to select any color from the grid, the popup disappears and the chosen color is not selected. Color in the document also does not change. In fact any mouse click in that popup (color grid scrollbar, checkbox, buttons, etc.) closes the popup without interacting with its contents at all. The popup controls work fine when using keyboard (Tab, arrows, Enter) to navigate and select color. This worked perfectly fine before, so it is a (very problematic) regression. Affected versions: Writer 7.2.1.2, Calc 7.2.1.2 (Kubuntu 21.04 packages)
