Previously we were setting the property again in it's setter. This is obviously not a great idea. CL 109641 changed ivar accesses in blocks to property accesses and this bug got introduced there. Bug: webrtc:10110, webrtc:10127, webrtc:9971 Change-Id: I01abb0885b3bfc91fb741d82d1ece015ee9d3b58 Reviewed-on: https://webrtc-review.googlesource.com/c/116062 Reviewed-by: Peter Hanspers <peterhanspers@webrtc.org> Commit-Queue: Kári Helgason <kthelgason@webrtc.org> Cr-Commit-Position: refs/heads/master@{#26124}
