When viewing the results for the Affects Bundle Custom Field (and presumably also the Fixed In Bundle Custom Field), the results are not paged.
This has client-side implications where one of our Affects Versions belongs to hundreds (or thousands) of bundles.
At worst, the client lags due to waiting on network or server resources. At best, the client has to scroll quite a lot.
I'd post a picture but it would contain a lot of internal information. But as an example, one of our component versions belongs up to nearly 2400 bundles. Displayed in the browser, it spans 3 screen heights (15 inch Mac Pro).
