a bit more in detail:

when a link-to is wrapped with {{#active-link}} and the link-to has a dynamic title then changing the dynamic title value twice will cause a rerender assertion error on Ember v2.10

[Turbo87]

temporary workaround: put a <span title={{dynamicThing}}> inside the link-to and remove the title from the link-to itself
