Javascript highlighting fails when less than symbol ("<") is first char and followed by greater than (">")

TS and JS Grammar Extension version: clicking previous link (in chrome 91.0.4472.114 on macos 10.13.6) gives 404 but searching vscode 1.59.1 extensions for @builtin typescript shows vscode.typescript-language-features 1.0.0 and vscode.typescript 1.0.0. Installing ms-vscode.vscode-typescript-next 4.5.20210902, found in this repo's readme, made no difference.

Code

vscode language mode: JavaScript

const x = 1;
0
< x
&& 1 > 0 // incorrect syntax highlight color coding

The issue seems to be that < x … > is interpreted as some type specification (like in array<int>)?
Compare with following where the last x is replaced with 1.

const x = 1;
0
< 1
&& 1 > 0 // correct syntax highlight color coding

I found #752 but decided to open a new issue.

Start with the JavaScript grammar behavior for the reproduced < x and && 1 > 0 expression, then compare it with the numeric variant in the issue. Review the related #752 issue and the grammar files in this repository to identify the relevant rule. Done means both examples receive correct JavaScript syntax highlighting.
