Description Diego Pino 2020-06-13 14:02:30 PDT
Many tests started failing in GTK Release (Tests) build #14065 (https://build.webkit.org/builders/GTK%20Linux%2064-bit%20Release%20%28Tests%29/builds/14065)


There are only two revisions in the build. I bisected the revisions and verified the failures started happening in r262994.

Sorry, just noticed this.  Will look into it tomorrow.  (Also forgot that GTK tests aren't run by EWS.)

I wonder if we just need to provide a default initializer for WebCore::PluginInfo::clientLoadPolicy (and ::isApplicationPlugin while we're here):

Thank you David. Your patch fixed the regression (I run the tests locally to verify it).
