Memory leak when trying to add an internal link in Chrome

[dkalpakchi]

Issue Summary

I am trying to add an internal bookmark in Chrome using a feature highlighted here: https://ghost.org/changelog/internal-linking/. By mistake I found my Chrome tab freeze and consuming a lot of memory (and using a lot of CPU) until the tab crashed with the segmentation fault.

Steps to Reproduce

1. Start a new post in Ghost admin
2. In a new paragraph type @. This should create a Find a post, tag or author menu
3. Now click backspace
4. Now type @ one more time
5. The tab is frozen now
