Description
There's an issue with the last few versions of Chrome that cause accessing the innerText of an element to take significantly longer than before (~70x in my testing). This causes problems performing highlighting on large datasets due to to this line:
https://github.com/bevacqua/horsey/blob/master/horsey.js#L392
In my case, processing a 3000 character response causes Chrome to freeze for approx. 6000ms.
This looks like it will be fixed in a future version of Chrome, so likely doesn't need a long term patch in horsey. However, if anyone is facing this issue and needs an immediate fix, a workaround is to remove innerText from the line above and rely solely on textContent.
