Running tests via extension does not recognize custom selector

[dajester2013]

In playwright.config.js, I've started working on a custom selector for ExtJS:

const { selectors } = require("@playwright/test");

selectors.register("extjs", function() {
	return {
		query(root, selector) {
			if (window.Ext && Ext.ComponentQuery) {
	
				let rs = Ext.ComponentQuery.query(selector)[0];
				return (rs && rs.el && rs.el.dom) || null;
			}
		},
	
		queryAll(root, selector) {
			if (window.Ext && Ext.ComponentQuery) {
				let rs = Ext.ComponentQuery.query(selector);
				if (rs.length)
					return rs.map(r => r.el && r.el.dom);
			}
			return [];
		},
	};

});

Example usage:

page.locator("extjs=viewport").waitFor();

Running from the command line works as expected, tests pass normally. However, trying to run from the vscode extension errors with the message:

Unknown engine "extjs" while parsing selector extjs=viewport ...
