QInput inside QTree header loses focus when clicked on

[Sonit]

When i insert QInput inside Qheader, it loses focus, when i click on header with Input. QInput inmmediatly fires focus event and after that - blur event. How can i prevent this behaviour to make QTree editable? Thanks

P.S. I think this happend because of this code in QTree source (line 571):

__onClick (node, meta, e, keyboard) {
keyboard !== true && this.__blur(meta.key)
}
