[v2] Table of content does not render links when H1 is missing

[janssen-io]

Description

When the page does not contain a level 1 heading (# My Heading), the table of contents renders the markdown links as plain text.

Details

Only present in SilverBullet v2 (tested on 771c160)

Steps to reproduce

1. Create a new page
2. Enter the following markdown

## H2 - 1
## H2 - 2
## H2 - 3

3. Reload the system or page
4. The table of contents now shows the following as plain text:

  * [[index#H2 - 1|H2 - 1]]
  * [[index#H2 - 2|H2 - 2]]
  * [[index#H2 - 3|H2 - 3]]

5. Add an H1 above the first H2:

# H1
### H2 - 1
### H2 - 2
### H2 - 3

6. Now the table of contents renders the links nicely

 * H1
   * H2 - 1
   * H2 - 2
   * H2 - 3

Notes

• Putting the H1 below one of the H2's will render only the H1 and the headings below it nicely.
• Edge (v1) renders the TOC nicely, even without a level 1 heading present.

Yeah I noticed this, thanks. The Lua implementation isn't as robust as the typescript one.
