Unable to link to headings, and Outline disappears or stops updating

Steps to reproduce

Unfortunately I don’t know what conditions are needed.

  • It may be more likely with a long note.
  • It seems to me that the problem happens less often when Restricted Mode is activated. Maybe try to reproduce on a device with constrained RAM in a vault that uses a lot of it. Using a long note may also

Setup:

  • Have at least 4 notes with headings.
  • Open 2 of them in the same tab group.

When the conditions are right:

  • Try to link to a heading in the current note: [[#(probably linking to any heading anywhere works, but this is my usual case).
  • Open the right sidebar and (if it’s not already open) switch to the Outline.
  • Add a new heading.

Further:

  • Switch to another note and repeat.
  • In the original tab, navigate to a different note and back.
  • In the second note’s tab, open the original note.
  • In the second note’s tab, open a note that hasn’t been opened yet in the current session.
  • In a new tab, open the original note.
  • In a new tab, open the second note.
  • In a new tab, open a note that hasn’t been opened yet in the current session.

Expected result

  • Link suggester offers headings.
  • Outline shows the note’s headings.
  • Outline updates to include new heading.

Actual result

  • Link suggester offers no headings in existing tabs. In new tabs it at least sometimes offers them in notes other than the original.
  • Outline shows no headings in the first note. They may be missing in other notes too, but in my test while writing this up they only disappeared from the first one.
  • In notes where the Outline shows headings, it doesn’t update to include new ones.
  • In the first tab, navigating to another file and back doesn’t fix the problem.
  • Opening the first note in a new or existing tab doesn’t fix the problem.

Reloading the vault fixes the problem until the next time it happens.

Custom theme and snippets: for cosmetic issues, please first try updating your theme and disabling your snippets. If still not fixed, please try to make the issue happen in the Sandbox Vault or disable community theme and snippets.


Additional information

This has been happening for a while prior to the current version; sometimes more often, sometimes less. Until now I haven’t had the patience to run in Restricted Mode long enough to verify that the problem happens there too. In this case I enabled it on 1 device, encountered it on another device and enabled it there, and then I think the problem arose in the next 1–3 days (unfortunately I didn’t think to track it).

My vault has 6,275 files and 415 folders, and I believe enough links to push me into the simplified Quick Search / link suggestion algorithm.
