jquery: Bug of find element with empty attribute in v3.4

Description

Hi. After updating jQuery to 3.4, I encountered strange behavior on Edge and IE11.

Finding elements with empty attributes was successful in v3.3. But, v3.4 and later will fail on Edge and IE11.

<div id="test">
    <input name="">
</div>

var $input = $("#test").find("[name='']");

console.log($input.length); // This will return 0, only on Edge and IE11 after updating to v3.4

If this is a bug, I’m glad if a fix is considered. Thanks.
