Keyword pane no longer keeps all the words inside the pane

I have been using Photoshop for many years now and rely heavily on the metadata feature, especially the keywords pane. I upload photos to microstock agencies, so keywords are crucial. Typically I enter from 40 t0 50 per image. In the past, this worked flawlessly. When the number became too many for the short pane to show them all, it could simply be expanded downward. With the recent update, however, this no longer does the trick. The keywords disappear outside of the pane to the right or left, and I have to constantly move back and forth to see the hidden ones. Even expanding the box doesn't keep them all inside. That makes keeping track of them difficult and more time-consuming. Has anyone else encountered this? Any way to get them to stay inside the pane? Thanks.
