Comparison operators ("<", ">") incorrectly interpreted as type parameters

TS and JS Grammar Extension version: 0.0.55 / latest

Code

// Contrived because of simplification
let a = 7
let b = {}
if (a < (b as {c: number}).c || a > (b as {c: number}).c) {

}

If statement parsing:

if [keyword.control.conditional.ts, source.ts]
( [meta.brace.round.ts, source.ts]
a [entity.name.function.ts, meta.function-call.ts, source.ts]
< [punctuation.definition.typeparameters.begin.ts, meta.type.parameters.ts, source.ts]
( [meta.brace.round.ts, meta.type.paren.cover.ts, meta.type.parameters.ts, source.ts]
b [entity.name.type.ts, meta.type.paren.cover.ts, meta.type.parameters.ts, source.ts]
as [entity.name.type.ts, meta.type.paren.cover.ts, meta.type.parameters.ts, source.ts]
{ [punctuation.definition.block.ts, meta.object.type.ts, meta.type.paren.cover.ts, meta.type.parameters.ts, source.ts]
c [variable.object.property.ts, meta.definition.property.ts, meta.field.declaration.ts, meta.object.type.ts, meta.type.paren.cover.ts, meta.type.parameters.ts, source.ts]
: [meta.type.annotation.ts, meta.field.declaration.ts, meta.object.type.ts, meta.type.paren.cover.ts, meta.type.parameters.ts, source.ts]
number [support.type.primitive.ts, meta.type.annotation.ts, meta.field.declaration.ts, meta.object.type.ts, meta.type.paren.cover.ts, meta.type.parameters.ts, source.ts]
} [punctuation.definition.block.ts, meta.object.type.ts, meta.type.paren.cover.ts, meta.type.parameters.ts, source.ts]
) [meta.brace.round.ts, meta.type.paren.cover.ts, meta.type.parameters.ts, source.ts]
. [meta.type.parameters.ts, source.ts]
c [entity.name.type.ts, meta.type.parameters.ts, source.ts]
| [keyword.operator.type.ts, meta.type.parameters.ts, source.ts]
| [keyword.operator.type.ts, meta.type.parameters.ts, source.ts]
a [entity.name.type.ts, meta.type.parameters.ts, source.ts]
> [punctuation.definition.typeparameters.begin.ts, meta.type.parameters.ts, source.ts]

(rest is normal)

So like:
if ( a<type>(parameters).c ) {}

Example in vscode:

Actual code:

Comienza con la TypeScript and JavaScript Grammar Extension y reproduce el fragmento indicado en VS Code usando los ámbitos de sintaxis mostrados en el issue. Rastrea cómo se clasifican los operadores de comparación en la gramática; se considera terminado cuando \u003c y \u003e siguen siendo operadores de comparación, mientras que la aserción de tipo circundante y el acceso a la propiedad reciben el resaltado normal.
