Ensure toolbar stays visible for large images in ImageEditor

[hannahblair]

Description

Large images were causing the toolbar from being pushed down outside the container, and check that the behaviour is consistent when changing the height of the container.

To test, upload super tall images and test crop. Note there are still some other known issues around ImageEditor which I'd prefer to fix in another PR. e.g:

• Zoom is needed for large images because it becomes too small to edit easily
• Cropping is behaving strangely when the crop ratio isn't 1:1 (see here)
• Choosing webcam sources is buggy
• Colour change selection not working

Please do mention anything else you notice that's not been flagged 🐛

Closes: #9694

Nice @hannahblair ! For me, every image upload was causing the toolbar to disappear so this PR definitely fixes it!

I noticed that all images are now the same size in the image editor (see gif), is there a way to control that?

Also, I think the right issue to close is #9694

Otherwise, let's fix the lint and get this in!

[hannahblair]

thanks @freddyaboulton! I've actually increased the max height threshold which prevents any overflow still so your larger images should be scaled a bit more. The images aren't necessarily the same size but if they're greater than the max_height then they'll be capped at that the max_height.

Great thanks @hannahblair !!
