Steps to reproduce:

• Firefox 48
• I am logged in to Gerrit.
• Go to https://gerrit.wikimedia.org/r/#/c/311956/ (currently "Needs Code-Review")
• I click on "Owner: Abc123" in the table at the top center
• I end up on https://gerrit.wikimedia.org/r/#/q/owner:Abc123+status:open

Expected results:
Get list of open changesets with user Abc123 as owner.

Actual results:
Four changesets shown, all of them with Owner "Matěj Suchánek" instead of "Abc123"

Other comments:
Entering owner:"Abc123 <tomstarc123456@...." in the search box shows correct results (two changesets shown). [Replace .... by gmail here.]
