If a rabbit hops into the same block as a glass pane, they'll get stuck and not be able to move anymore. Just constantly hopping there. Sometimes they're able to get back out, but often times they're stuck until the block is broken.
There's an existing "rabbit gets stuck in glass" issue, but that appears to be more in regards to glass blocks, not panes.
