The update of styles previews is probably less important thatn the update of the document area, so in case this stays in the TaskPriority::HIGHEST -> TaskPriority::REPAINT region, that's potentially problematic. In practice for example a LOK client may decide to register its anyInput callback to stop idle jobs in case no high priority jobs are scheduled on the main loop, and this would delay paintTile() calls due to this idle.
