Notebooks load much slower than they used to

[akhenry]

Summary

Notebooks appear to show no entries for a period while loading, which can give users the false impression that their entries have been lost. This appears to be due the UI blocking while tags are fetched. There is no need to block entries from loading while tags are fetched, the tags should be fetched in parallel and "layered" on when availabe.

Expected vs Current Behavior

Notebook entries should display as soon as available and not block until tags are fetched.

Steps to Reproduce

1. Load a notebook with some entries
2. Observe that the notebook loads but appears to be empty (ie. no entries) for several seconds until the entries eventually appear.

Environment

• Open MCT Version: 2.2.5
• Deployment Type: MMOC

Impact Check List

• Data loss or misrepresented data?
• Regression? Did this used to work or has it always been broken?
• Is there a workaround available?
• Does this impact a critical component?
• Is this just a visual bug with no functional impact?
• Does this block the execution of e2e tests?
• Does this have an impact on Performance?

Additional Information

Perhaps something slow in pulling tags from Couch?

[akhenry]

This appears to be fixed for unknown reasons (possibly the Vue 3 refactor). Closing to retest.

Testing instructions

1. Follow the reproduction steps in the issue
2. Confirm that Notebook entries appear immediately when the notebook loads, and that tags are loaded in later.
