The "Click to activate Flash" box from Chrome stomps on the title
attribute of a Flash embed when you mouse over it. This causes
an annoying "Adobe Flash Player" tooltip to appear even after
Ruffle replaces the embeds.
Now we check for this specific title and remove it.
Ruffle would not polyfill a Flash embed if it had bogus attributes
in the embed tag. Now these errors are silently ignored.
Fixes the other part of #457.
Fixes part of #457. Even if the MIME type/class IDs are missing
on the embed/object tags, browsers will still attempt to play
the file as Flash if it ends in a .swf extension.
When a Ruffle player element is disconnected, attempts to play SWF files
fail semi-silently.
We also check for nested objects, since only the top should be
successful in loading.
Instead of forcing a chunk load on Webpack just so we can have Webpack prepare the WASM for us, we're now using the `no-modules` mode of `wasm-pack` manually and loading the resulting files ourselves.
I still have to force Ruffle to load outside of the extension sandbox though...
