Chrome+Vue 2 = multiple select items not selected correctly

[lauri911]

Addition to issue #3852 via f9bef75.

When I opened issue #3852, there was also another problem, I did not know was they related or not.

Looking at solution f9bef75, I tried it right away --- multiple selections don't work as they should:
only last item is selected from preselected items.

PS. Vue 1 works fine, I already downgraded my apps :)

When pathing dom, the mutliple attribute of select dosen't apply at first, so the mutli selected option dosen't work.
