[orca-list] Loosing focus after clicking on a JS link

[Raphaël POITEVIN <rpoitevin hypra fr>]

Dear team,

Debian Stretch, Orca 3.26, Firefox Nightly 58.0a1

Steps to reproduce:
1. Go to this URL: 
http://parlonspiano.com/lieu-avec-piano/627/centre-de-musique-frederic-hasselmann
2. go to the link "plus" and press enter to activate it
3. continue to browse the page with arrow keys

Expected result: we should be able to move in the page
Actual result: the caret is locked.

Note that bug doesn't appear when activate the link with a Braille 
routine cursor.

Regards,
--
