Subject: 31.0.50; eww-list-buffers replaces other buffers' contents
Date: Wed, 16 Apr 2025 20:36:18 +0000

For some reason, eww-list-buffers keeps trying to replace the contents
of different buffers with the contents of its own buffer. Here's how to
reproduce on master with emacs -Q:

1. M-x eww to any URL
2. M-x eww-list-buffers
3. Open any file
4. M-x revert-buffer on that file's buffer

You should see the contents of eww-list-buffers rather than the contents
of your file.
