Selector: escape sequences with spaces not allowed in unquoted identifiers #4424
Description
Description
Escaped selectors for attributes don't work using "find()", but they work using "$()".
I would understand if they never worked, but I assumed "find()" and "$()" were doing the same thing...
As a workaround I'm quoting the value, but it's surprising.
Updated to jQuery 3.4.1 a few minutes ago.

var selector = '[data-id=' + $.escapeSelector('0_some_$id') + ']';
console.log($(selector).length);
console.log($('html').find(selector).length);Output:
