parents(selector) does not find ancestors by selector

[gormster]

Bug report

parents(selector) does not behave as expected. It does not always terminate at the closest matching ancestor; instead, this behaviour only occurs if the first element matching the selector in the document is a direct ancestor of the calling element.

Fiddle

Explanation

Expected behaviour

parents(selector) should return the ancestors of the current element up until an element that matches selector, as documented. In the supplied fiddle, both circles should turn green.

Actual behaviour

The returned list of elements only terminates if the first element in the document that matches selector is a direct ancestor of the calling element. In other words, if element.root().findOne(selector) is in element.parents(), then element.parents(selector) works (almost) as expected. However:

• If there are multiple elements in the parent chain that match the selector, parents(selector) matches the furthest element, not the closest one (https://jsfiddle.net/gormster/erhwjv1c/)
• If there are multiple elements in the document that match the selector, and the first such element is not in the parent chain, parents(selector) returns all parents including the elements in the containing HTML document (https://jsfiddle.net/gormster/2xw7sape/)
• If there are no elements in the document that match the selector, parents(selector) throws a TypeError (https://jsfiddle.net/gormster/c7k23vt0/)
