Writing a statement with f4, placing it and then undoing twice causes the text to appear outside the borders, starting at the top right of the level (I put one invalid word at the start to make the screenshot prettier). This is a minor bug and the text is deleted when the test button is selected but it might be worth fixing. The same does not appear to happen with any other multiple object selection.
The text in the screenshot is supposed to say "text s h o u l d not b e h e r e" but some text is not visible for some reason.
