Auto Suggestion for links to nested subheadings does not work when headings have [[ in the name

[kevinawoo]

When I invoke the link suggestion modal, it fails to list any headings if the parent heading contains an existing link.

Steps to reproduce

The example note:

[[#Normal Heading 1#Normal Heading 3]]
[[#2024-06-27#

# Normal Heading 1
## Normal Heading 2
### Normal Heading 3



# [[2024-06-27]]
## heading 2 under date
### heading 3 under date

1. copy the example note
2. invoke the heading link to line 10 # [[2024-06-27]]
3. notice there’s no suggestions for any nested headings

Did you follow the troubleshooting guide?

Yes, tried it in the sandbox vault

Expected result

This screenshot shows what I’d expect to see from the dropdown modal. Normal Heading 2 and Normal Heading 3 is show.

Actual result

In this screenshot, it seems like Obsidian recognizes 2024-06-27 as a heading (stripping [[), but when suggesting, it doesn’t know there’s nested headings.

I haven’t tested other characters, but my guess is any formatting characters cause the same issue as well.

Formatting characters do not cause the issue - they are taken over in the display text. The auto suggestion algorithm thus continues to recognize the text elsewhere in the document. In the case of a link, the characters are removed, thus the string becomes different: # [[2024… becomes # 2024…. The code for retrieving the auto suggestions would need to be complicated somewhat to account for that possibility.
