Exception in DiagramCanvas due to race condition

[toluwtglobal]

In DiagramCanvas reference error is thrown when un-subcribing from resize event during dispose. This is cause by race conditions as the method is executing synchronously. WE have created a PR for making the execution asynchronous. See PR link below.

Hi, I got the same issue, but even with the changes in the pullrequest I sometimes get an exception by the canvas already being disposed when calling ObserveResizes. Checking if the Canvas has been disposed before fixed this.
