[FIX] web_editor: prevent crash on link edit

Go to Website
Go to conatct us form
Switch in Edit mode
Click on “send” (or "submit")
click on edit link

A js traceback will apper. This occur because we refocus an elements
which may not be the correct one. In this case $editable will contain
all the contact form instead of just the relevant div of the submit
button
