Public bug reported:
Chrome only supports app-modal JS dialogs, and so does Blink
(window.alert blocks the calling process).
Oxide pretends to support tab-modal JS dialogs by having a per-WebContents
dispatch queue. However, the behaviour is quite broken:
- It's really app-modal in single process because there's only a single
RenderThread.
- In multi-process it's not really tab-modal - it's render-process modal (ie,
only a single tab in a render process can show a JS dialog). So, if 2 tabs live
in separate processes then they can display JS dialogs at the same time. But if
they're from the same SiteInstance and live in the same process, they can't.
We should just change the dispatch of JS dialogs to be application modal
instead, so it behaves consistently in all configurations.
