For a few months I've been duplicating / branching off the same project for all new projects. What I recently noticed is that the file size of the original project kept increasing. It only contains some basic custom elements, and was originally around 1 MiB in size. Now (before I deleted it), it was around 36 MiB. It turns out that the size of all new projects adds to the original project.
This bug is easy to recreate. Just duplicate a site that contains something, and notice how the size of the original will increase. Is this bug only a number error, or is the website actually increasing in size? If so, how can I remove those weird MiB being added to my original project (and all new projects after duplicating it)?
