Version of jquery in dependencies is malformed?

[SpecialK118]

It looks like the dependent version of jquery is malformed in the jquery-ui/package.json file

"dependencies": {
	"jquery": ">=1.8.0 <4.0.0"
},

the python package semantic_version (last version - 2.10.0) is unable to parse it and throws the following error:

File ".../semantic_version-2.10.0-py3.8.egg/semantic_version/base.py", line 1225, in __init__
  super(LegacySpec, self).__init__(expression)
File ".../semantic_version-2.10.0-py3.8.egg/semantic_version/base.py", line 647, in __init__
  self.clause = self._parse_to_clause(expression)
File ".../semantic_version-2.10.0-py3.8.egg/semantic_version/base.py", line 1043, in _parse_to_clause
  return cls.Parser.parse(expression)
File ".../semantic_version-2.10.0-py3.8.egg/semantic_version/base.py", line 1063, in parse
  raise ValueError("Invalid simple block %r" % block)
 ValueError: Invalid simple block '>=1.8.0<4.0.0'

There are multiple tickets for this in semantic_version package, in which the maintainer claims this is not a valid NPM notation:
rbarrois/python-semanticversion#99
rbarrois/python-semanticversion#127

Could it possibly need to be ">=1.8.0, <4.0.0"?

It seems okay based on the description at https://github.com/npm/node-semver?tab=readme-ov-file#ranges

Comparators can be joined by whitespace to form a comparator set, which is satisfied by the intersection of all of the comparators it includes.

If there is a less ambiguous or more authoritative BNF grammar for this, I wasn't able to find it in 30 seconds of searching.

The form used in our package.json is actually a normalized form that packages like semver use as a base, converting all the other forms to this one internally.

If you parse this field, make sure to use a tool that understands the semver standard.
