Previously, on a changelist or file view, if you change the patchset to a lower number and then click the back button, dropdown value did not change properly. The issue was related to how the selected option was rendered in a dom-if. This change refactors the gr-select element to fit this use case. Bug: Issue 4800 Change-Id: I66ee5b7aba5421a01ca79f9e72a853a73c32e589
