Assets web page memory leak

Dagster version

What's the issue?

Keep the /assets page in chrome opened for a while. Open dev tools and you will see the memory steadily increasing. After a while, the tab in chrome crash with an out of memory exception. This can take several hours.

Thanks for bringing this to our attention, @EtienneT -- I've confirmed that I experience the memory leak as well.

When using the Task Manager in Chrome, you can clearly see the number rise.

And using the Memory profiler in the developer tools, we can compare the object allocation between two heap snapshots and see in more detail where things are being allocated.

We'll dig into this further - thanks.

Edit: I also confirmed that it only appears to grow when the tab is focused, and not in the background.

Thanks for the report, the fix will go out in our release this week
