Image column is too tall, thumbnails in one row move when clicked in another

I have a table where all of the rows are ‘too tall’ for the content. In an image column, the thumbnails display in the lower section of the row. Interestingly, if I double click in the dead space, above the thumbnail (as if I am trying to expand a thumbnail that isn’t there), it moves the thumbnails in the row below. In this gif I am clicking back and forth between the two different rows and you see the thumbnails ‘dancing’:

Using style overriding browser extensions makes this really difficult to know if it’s happening in Coda or if it’s something happening from the browser extension.

If you can show the same thing happening with these browser extensions disabled, then we can look.

Hmm they dont ‘dance’ in Safari, but they are aligned to the bottom still:
