Pasting non-oembed urls has unexpected behaviors

[Ipstenu]

In visual editor only.

1) Pasting a non-oembed URL on it's own causes an embed to 'flash' before putting in the URL. However it ALSO returns your cursor to the top of the page, which is really bad for accessibility

2) If you paste in multiple non-oembeds, one of them will eventually get stuck: ​https://cloudup.com/cJr27fOB96i

3) If you tab between visual and text enough times (twice in my checks), you'll get stuck with ALL non-oembeds acting like this: ​https://cloudup.com/cZJJ3gv2Cbp

The URL I was pasting in was ​https://wordpress.org/support/topic/40-beta-4-oembed-behavior-with-multiple-non-oembed-urls?replies=1&view=all (which is also where this was initially reported)

Tested on TwentyFourteen with no plugins active.

I can't reproduce 2, but 3 happens for me in FF 31.0.

2 happened after 3 links, and not before, on Chromium 36.0.1985.125 (0) on Mac

I initially reported this one. I forgot to say that I'm using Chrome 36.0.1985.143 (Official Build 287914) m on Windows 7 64 bit. Not sure if that matters, but hopefully it helps.

That should fix it. We shouldn't replace the urls with a loading placeholder in the first place, but it's a bit late now to try other things. I'll open another ticket for that for the next cycle.
