Change subject: Add $wgMFStripResponsiveImages setting, defaulting back to off
......................................................................
Add $wgMFStripResponsiveImages setting, defaulting back to off
Introduces $wgMFStripResponsiveImages setting, defaulting to off
to restore previous default behavior of not removing srcset attributes
on the mobile view.
Also adds the setting to the parser cache hash key -- previously,
srcset would be stripped from the parser cache on mobile *renderings*
but still *served to desktop* or vice versa.
Bug: T134115
