setTimeout (called on keydown) changing a property on a controller prevents typing in a field

[divdavem]

Consider the following file (which is an extract of an autocomplete component). Try typing something in the field.

HSP file

var klass = require("hsp/klass");
var $set= require("hsp/$set");
var Ctrl = klass({
    keyDown: function () {
        if (!this.myTimeout) {
            var self = this;
            $set(this,"myTimeout", setTimeout(function () {
              $set(self,"myTimeout", null);
              // ...
            },5));
        }
    }
});

# template myTemplate using c:Ctrl
      <input onkeydown="{c.keyDown()}" value="{c.value}">
# /template

myTemplate().render("output");

Expected behavior

The input field contains what was typed.

Actual behavior

The input field does not receive all typed keys.
