## With AMC enabled:
Click the history link
I should see the history page from desktop in all its unstyled messy glory (there is a form at the top of the page)
## With AMC disabled
Click the history link
I should not see the form at the top of the page
## anonymous
Click the history link
I should not see the form at the top of the page
# developer notes
The override happens in a hook where config and amc can be checked
Earlier attempt: https://gerrit.wikimedia.org/r/#/c/mediawiki/extensions/MobileFrontend/+/487071/
We should retain all other special page optimisations and limit our changes to the [[https://github.com/wikimedia/mediawiki-extensions-MobileFrontend/blob/master/includes/specials/SpecialMobileHistory.php#L89|SpecialMobileHistory::shouldUseSpecialHistory]] function.
