Steps to reproduce the problem:
1. Create a nodejs heap dump (should have the .heapsnapshot file extension).
2. In dev tools under the javascript profiler try to load the .heapsnapshot file.
3. You will get an error that states "Can't load file. Only files with extensions '.cpuprofile' can be loaded."

What is the expected behavior?
I would expect to be able to load .heapsnapshot files, as this was supported in the past.

What went wrong?
The heap dump was not able to be viewed.

Did this work before? Yes Not sure.
