Image Properties -- Bigger text box for Alt Text

My org is trying to keep our docs accessible, and one of the requirements is using alt text on most images. I keep finding this difficult to do because the text box for entering the image's title and alt text is so small. I can only view part of the sentence, so in order to proof what I just wrote I have to exit the properties screen. Then, hover over the image to make sure I didn't introduce typos. If I did, then it's edit the image > Properties > edit text all over again. Wash, rinse, repeat.

It would be super helpful if the Title and alt text input boxes were much bigger.
