A silly hack for window.open in Safari with DragonRuby. Append this to the end of `.dragonruby/stubs/html5/dragonruby-html5-loader.js`.
// .dragonruby/stubs/html5/dragonruby-html5-loader.js
// ...
// end of dragonruby-html5-loader.js ...
// A silly hack for Safari browsers to get `window.open` to behave properly.
// The hack is fairly straightforward. We create a "hidden" anchor. When the user clicks on the page, if `window.open` gets called
// in a "click" event, it will set the `href` and `target` attributes on the anchor, and then when the `pointerup` finishes, reverts
// the override on `window.open` and remove the `href` and `target` attributes.
//
// As for "why" this works, Safari as part of "security", generally only expects `window.open` to be called in "click" and "click-like"
