Thread:Extension talk:Maps/Maps3.0 not compatible with browser on commit

I've been having an interesting problem with Maps 3.0. The map preview (preview before committing a change) works fine, but the actual page shows "Your browser is not compatible with Google Maps v3.". Then, after several days, it starts displaying just fine, until another commit, when it goes back to not being compatible. This happens at least on chrome and firefox, both on Ubuntu 13.10, I'm not sure about others.

Info:
 * url:

 * Mediawiki: 1.22.0
 * Maps: Version 3.0-RC1 (5e3e925)

I have already checked, and this is not due to the old issue at Thread:Extension talk:Maps/SSL and grey boxes
