Please describe the problem:
When i set the key "layout.spellcheckDefault" to "1" inside about:config Epiphany marks misspelled words with a red line, like Firefox, gedit etc. Usually you can click with the right mouse button onto those words and inside the popup menu you can select alternatives which might correct your spelling mistakes. But Epiphany doesn't show anything. Just the usual copy and paste actions.

Steps to reproduce:
1. Activate spellchecking with "layout.spellcheckDefault=1" inside about:config
2. Type "teest" inside a textbox, e.g. at bugzilla.gnome.org
3. Click with the right mouse button onto the marked text


Actual results:
Nothing, no alternatives visible

Expected results:
Epiphany should give me a list of possible alternatives like e.g. gedit

Does this happen every time?
Yes
