Annotation guidelines can be lost

[Tradunsky]

How to reproduce the behaviour

1. Put guidelines when network is stable
2. Turn off the network (simulate network issues)
3. Put guidelines when network is unstable

Expected result: guidelines saving progress showed and when it times out it showed as failed. Actual result: Since no saving progress is shown a user can navigate to another page or close the tab and lost his changes.

Your Environment

• Operating System: Linux
• Python Version Used: doccano docker
• When you install doccano: half a year ago. Tested the same on the latest version.
• How did you install doccano (Heroku button etc): doccano docker.

Some additional observation to help with UX: Some users' network performance can be poor or sometimes even not stable, would be great to have youtube like request pre-loader indicator at the top (like the red line) and if it times out or fails - rollback changes on UI and show an error popup.

If that's not a lot of work 🙏🏻

@Hironsan : Facing the same issue. Unable to save the Guideline. Did you get a chance to fix this ?

Even though, I have a stable network, Guideline doesn't save. Not sure, what can be done as a work around too.
