Lens panel is loading endlessly

[AlonaNadler]

I created a lens panel, saved it, then clone it.
The cloned panel I edited in Lens and click back without saving.
When I go back to the dashboard it loads without ending (small dataset)

Hi @AlonaNadler I tried to reproduce this issue with master with one of the example datasets and I couldn't. All works well for me. I could really use a few additional information here:

1. kibana version
2. did you create it straight from the dashboard or in visualize?
3. is there any error visible in the console?
4. Can you reproduce it with any lens visualization? If not, what is the visualization you used?
5. Is there any failed network request in network chrome tab?

I used two-layer mixed chart trying to make it as similar as yours:

After speaking to @AlonaNadler I found out that it only happened once and couldn't be reproduced by her. It can be a real bug, or maybe a browser error or a server was killed in the meantime? Till it happens again, I'll close this issue. Feel free to reopen once we know more.
