          Issue Type: Bug
          Components: wicket-core
    Affects Versions: 9.11.0
         Environment: - macOS 12.5.1 (intel)
- Tomcat 8.5.82

I have a simple form with a TextField and an AjaxButton. The button is disabled initially and is being enabled after typing something in the TextField using an OnChangeAjaxBehavior (see attached quickstart). Enabling the button works as expected.

However, when clicking on the button after the OnChangeAjaxBehavior has fired, the first click is ignored. It is only after a second click on the button that the onSubmit() method is triggered.

Looking at the JS console, it seems that the first click triggers another "input change" event due to the focus change:
{code:json}
{
  "u": "./?3-1.0-form-input",
  "m": "POST",
  "c": "inputd",
  "e": [
    "input change"
  ],
  "event": {
    "originalEvent": {
      "isTrusted": true
    },
    "type": "change",
    "target": {},
    "currentTarget": {},
    "timeStamp": 4471,
    "jQuery360038239900837477336": true,
    "delegateTarget": {},
    "handleObj": {
      "type": "change",
      "origType": "change",
      "data": null,
      "guid": 4,
      "namespace": ""
    },
    "data": null
  },
  "ch": "0|s",
  "wr": true,
  "dt": "xml",
  "async": true,
  "rt": 0,
  "pd": false,
  "sp": "bubble",
  "sr": false
}
{code}
After that, the next click triggers the "click" event as expected:
{code:json}
{
  "u": "./?3-1.0-form-submit",
  "m": "POST",
  "c": "submit10",
  "f": "forme",
  "sc": "p::submit",
  "e": [
    "click"
  ],
  "pd": true,
  "event": {
    "originalEvent": {
      "isTrusted": true
    },
    "type": "click",
    "target": {},
    "currentTarget": {},
    "relatedTarget": null,
    "timeStamp": 28490,
    "jQuery360038239900837477336": true,
    "delegateTarget": {},
    "handleObj": {
      "type": "click",
      "origType": "click",
      "data": null,
      "guid": 62,
      "namespace": ""
    },
    "data": null
  },
  "ch": "0|s",
  "wr": true,
  "dt": "xml",
  "async": true,
  "rt": 0,
  "sp": "bubble",
  "sr": false
}
{code}
It should be noted that the bug does not occur when you tab out of the TextField first.

Also, parent component AjaxFormComponentUpdatingBehavior does not seem to be affected by this bug.
