This look like it is supposed to be a fork, but it isn't?

And no commits have landed in almost 6 years.

Should we keep this around? Ping @dirkschulze.

Seen from MDN, Safari had given up the font-feature-settings CSS property since 6.0, this property require advanced typographic feature support for OpenType fonts, so I hope you can help them to get support for this property in WebKit, and making it available in newer version of Safari.

Additionaly, you can also try to get support or improve for @font-feature-values, font-language-override, font-variant, font-variant-alternates, font-variant-caps, font-variant-east-asian, font-variant-ligatures, font-variant-numeric, font-variant-position properties based on this work.

Hi.

Recently I launched a game website. When I'm alone on the server, I have no problem, but if I`m in with a few users [even just five users] on the same server the performance gradually drops. [This is happening to many users who using chrome.]
In the Chrome JavaScript profiler, there is a phenomenon that the proportion of (program) increases over time. If I click on another tab in Google Chrome and click on the My Site tab again, the portion occupied by (program) is to be initialized [it seems to be (idle)]. But soon the specs are down.
So I used chrome: // tracing / and found Canvas2DLayerBridge to grow. This phenomenon was not found until I had drawn more than a certain amount on the canvas. How can I handle this?

• There is no problem with other browsers (ie, firefox, opera).
• The client is fully developed in JavaScript.
• Test environment is Windows 7, Chrome version is 64.0.3282.140.

Here is the stack trace of crash report.
