Description

Affected Packages

core, markdown

Version(s)

3.13

Bug Description

console.log(parseAttributes('#2123 .foo'))
console.log(parseAttributes('#hello .foo'))
console.log(parseAttributes('#5hello .foo'))

produces

{ class: 'foo' }
{ class: 'foo', id: 'hello' }
{ class: 'foo' }

As parseAttributes is used by default this affects all markdown parsing more or less, at least nodes created by the official helper utils.

Expected Behavior

I.e. any id with a leading number gets stripped. Reading https://github.com/jgm/pandoc/issues/7920 i'm unsure what to conclude.

  1. If pandoc now allows ids to start with number, then it should be the same here
  2. If not, then a warning should be added here and elsewhere, as this behaviour is not necessariliy known to people.

Additional Context (Optional)

Contributor guide

Research direction
Examine the parseAttributes function in the core package, identify where IDs starting with numbers are stripped, and decide whether to adjust the regex to allow them or add a deprecation warning.
