LiquidHTMLSyntaxError false positive with dynamic html tag

The @shopify/liquid-html-parser package throws LiquidHTMLSyntaxError for the following code:

<{% if true %}div{% endif %}></{% if true %}div{% endif %}>

Full error:

SyntaxError: expected a letter, "{{", "wbr" (case-insensitive), "track" (case-insensitive), "source" (case-insensitive), "param" (case-insensitive), "meta" (case-insensitive), "link" (case-insensitive), "keygen" (case-insensitive), "input" (case-insensitive), "img" (case-insensitive), "hr" (case-insensitive), "embed" (case-insensitive), "command" (case-insensitive), "col" (case-insensitive), "br" (case-insensitive), "base" (case-insensitive), "area" (case-insensitive), "svg", "style", or "script"

I'd expect this syntax to be supported rather than throwing an error.

This syntax existed in older versions of the Dawn theme (example), although the theme has now been changed to work around it. This is how the issue presents in the theme editor:

Reproducible with:

• Shopify theme editor
• Programmatic use of @shopify/liquid-html-parser

Start with the @shopify/liquid-html-parser package and reproduce the reported dynamic-tag example. Trace how the parser handles the opening and closing tags, then verify that the snippet is accepted without a LiquidHTMLSyntaxError and that existing parsing behavior remains intact.
