Hi WebKit, I'd like to get WebKit's position on some changes that were recently made to the spec <https://github.com/whatwg/html/issues/5872> for window.open(). Chromium is planning to ship <https://groups.google.com/a/chromium.org/g/blink-dev/c/q6ybnmxxvpE/m/2snoh6wkAgAJ> these new behaviors soon. The chromestatus entry <https://chromestatus.com/feature/5663031909416960> has the full details, but in essence, this makes two changes to the spec. First is that a new windowFeature value, 'popup', can be used to explicitly trigger a popup (popup=1) vs. a window/tab (popup=0). The other change is that the BarProp.visible properties will all return the same values, true for tab/window, false for popup. We do not believe either of these changes should cause compat problems, but we'll monitor for bugs as we roll it out. These changes simplify the usage of window.open() and work toward better interop in this area. We're hopeful that you're supportive of this change. Thanks, Mason
