Using left, right arrow keys to navigate text around citations messes things up

[dmukhg]

If you open current master (3f0e082 as of writing), click on the text near a citation and then try to use the left or right arrow keys to navigate across a citation, the cursor blocks. This works perfectly in the hosted version of lens cdn.substance.io/lens-writer/.

Old (Hosted) Lens

Current master

From my digging around, it seems like window.getSelection() results have changed between the two len versions.

For old lens, window.getSelection() used to have a text node as its anchor node, while in the new ones, a span#text-property node is the anchor node.

FWIW, this problem is solved if we use Citation.static.isInline = false.

I have narrowed the problem down to https://github.com/substance/substance/blob/master/ui/TextPropertyComponent.js#L320 this function. Will report further as I find out more.
