[github-ps1304]

atfer updating to Grafana 9.4.7 the plugin isnt working anymore:
reproduce the issue - open a Dashboard with a flowchart panel - edit your flowchart with draw.io - in my case replace a picture - save the draw.io xml - you will see a blank screen.

Hello,

We also reproduce the same problem in Grafana 7.5.17, since this morning.
As a workaround, it seems that removing the mxfile and diagram (added when we save the diagram in draw.io window) xml tags in the Source Content (at the begining and at the end) allows the graph to be displayed

I had the same problem this morning, but this workaround fixed the problem.
Thanks @guliangsi :)
