Thumbnail preview not posting if you press enter on a comment too quickly
![thumbnail_bug](/uploads/ca365e57b89dac133e0df9216f82c881/thumbnail_bug.PNG) just type a comment with link and press enter super fast. This happens to me ALL the time. - [ ] We need to keep the keypress url resolution. It's inefficient from a request standpoint, but the interaction is nice. - [ ] On each key press, resolve the urls. Collect the successes by url, ignore the errors - [ ] Select the url preview that makes the current url in the comment/activity - [ ] On enter, make sure the request resolves like any other key press and then submit the commit
