After adding an image (jpeg) to a table cell, I cannot resize it. The table is not locked, all arrange options are greyed out. If I triple click the image, it gets a blue bounding box but has no resize handles. I cannot resize the table cell itself; dragging a handle has no effect.
You can reproduce the problem by creating a new document based on the invoice template, inserting an image from Insert -> Choose into a selected table cell.
