Zoom thumbnail of document image in transcription editor behaving unpredictably

testing notes (QA)

On the QA site, start working on a transcription or translation in the editor.

• [x] While drawing a new polygon, the top-left corner thumbnail should disappear.
• [x] Same should be true for drawing new rectangles.
• [x] After a drawing is finished and the annotation is created, the thumbnail should reappear.

Describe the bug The thumbnail in the top left of the image (used for Zooming and moving around) is behavin unpredictably. It prevents the drawing of polygonal annotation boxes (if the thumbnail covers over the part of the image on which one of the dots needs to be drawn) but then later for the same image it allows the annotation box to be drawn (and we're not sure what changed).

Expected behavior I want to be able to draw polygonal annotation boxes without the thumbnail getting in the way, whether this means there's a way to move the thumbnail out of the way, or to complete the box regardless of the position of the thumbnail.
