Bug

What's the current behavior?

Pasting " anywhere in slate throws the following error.

Here is a very basic jsfiddle where the error can be reproduced: https://jsfiddle.net/4wzp6hxa/3/

Tested on Windows in Firefox with the latest version of Slate

What's the expected behavior?

" should be pasted into the editor.

[darkyshiny]

Just noticed that if the string contains at least one space the error is not thrown. Ex. 'asd asd"'

Couldn't reproduce the bug on Mac in Chrome, Safari, or Firefox.
" pasted as expected.

Looked at it some more today and can only reproduce in Firefox think the error I had in Chrome was entirely different (Sorry yesterday was a looong day). Updated the original comment with a new error stack

Clarification: this seems to be the case in Firefox when copying a " character from within Slate, and then trying to paste it. Clipboard reveals:

<span data-slate-fragment="JTdCJTIyZGF0YSUyMiUzQSU3QiU3RCUyQyUyMmtpbmQlMjIlM0ElMjJkb2N1bWVudCUyMiUyQyUyMm5vZGVzJTIyJTNBJTVCJTdCJTIyZGF0YSUyMiUzQSU3QiU3RCUyQyUyMmtpbmQlMjIlM0ElMjJibG9jayUyMiUyQyUyMmlzVm9pZCUyMiUzQWZhbHNlJTJDJTIydHlwZSUyMiUzQSUyMnBhcmFncmFwaCUyMiUyQyUyMm5vZGVzJTIyJTNBJTVCJTdCJTIya2luZCUyMiUzQSUyMnRleHQlMjIlMkMlMjJyYW5nZXMlMjIlM0ElNUIlN0IlMjJraW5kJTIyJTNBJTIycmFuZ2UlMjIlMkMlMjJ0ZXh0JTIyJTNBJTIyJTVDJTIyJTIyJTJDJTIybWFya3MlMjIlM0ElNUIlNUQlN0QlNUQlN0QlNUQlN0QlNUQlN0Q=">"</span>

for mime text/html.

The problem was with the FRAGMENT_MATCHER regex matching the data-slate-fragment too greedily. Fixed in PR above.
