When I use the "Look up word" right-click menu option on a StackExchange comment in OS X, the system selects other text and looks that up instead:
Step 1: select a word in a StackExchange comment to look up
Step 2: right click & "Look up word"
Step 3: watch OS X select some other text next to yours and look that up instead:
How can I fix this?
I'm using OS X 10.10.5.
It appears to shift the selected text by 10 characters to the right in all cases, and happens in Chrome but not Safari.
