If you absolutely must add a new compile flag... then after adding it 
to WebKitFeatures.cmake, you can add enable it like so in 
OptionsGTK.cmake:

WEBKIT_OPTION_DEFAULT_PORT_VALUE(ENABLE_MEDIA_STREAM PRIVATE 
${ENABLE_EXPERIMENTAL_FEATURES})
WEBKIT_OPTION_DEFAULT_PORT_VALUE(ENABLE_SERVICE_WORKER PRIVATE 
${ENABLE_EXPERIMENTAL_FEATURES})
WEBKIT_OPTION_DEFAULT_PORT_VALUE(ENABLE_WEB_RTC PRIVATE 
${ENABLE_EXPERIMENTAL_FEATURES})

It has to be done separately for each port that wants the experimental 
feature enabled on bots.

This is discouraged, of course. It's better if you don't need a build 
flag at all. But that is how you can do it if you can't find another 
solution to this CSS properties issue.
