I am not sure what I'm supposed to see after which steps and how to compare. :(

On any page of Proofread's "Page" namespace, WikiEditor dialogs wouldn't work (dialogs for adding Links, Image, Ref, Table, Gallery as well Search/Replace dialog) that was also affecting User scripts which relied on that class, such as RefBar or SAETools (with later on, it was impossible even to preview changes before saving them).

I've sent workaround patch, created by User:HrantKhachatrian which was accepted, but is not yet released to Wikisources.

Core cause of this issue comes from this change, and I think it's best to solve it at core level. As I don't know enough about CONTENT_MODELS, I'd ask Tpt and WikiEditor maintainers to look at this, and WikiEditor to behave regularly on Page namespace, as it was before above mentioned July change.

That would be https://gerrit.wikimedia.org/r/174936 in case it matters.

Fwiw... dialogs seem to be working for the Page: namespace on test2 at least. see https://test2.wikipedia.org/s/b54

The built-in search & replace still doesn't work under IE(11) however. Pretty sure the IE release at the time (IE8?) wasn't working with the S&R dialog and it was excluded in the scripts (pretty much forgotten about since). Then again it could just be me & setup that's preventing it from loading somehow.

Working again with the roll-out of 1.25wmf10
