Tab key not working in popup in chrome extension

问题

I have created a chrome extension that has a popup with the following HTML markup in it:

<html>
<head>
<style>
body {
font-family: 'Open Sans',arial,sans-serif;
background-color: #E5E5E5;
font-size: 13px;
text-shadow: 0px 1px rgba(255, 255, 255, 0.5);
}
</style>
</head>
<script type="text/javascript">function sendRequest(s,r){
chrome.tabs.getSelected(null, function(tab) {
  chrome.tabs.sendRequest(tab.id, {search:s , replace:r}, function(response) {
    console.log(response.farewell);
  });
});
};
</script>
<body>

<label for="search">Search for</label><input name="search" id="search"></input>
<label for="replace">Replace with</label><input name="replace" id="replace"></input>
<button onclick="var s=document.getElementById('search').value;var r=document.getElementById('replace').value;sendRequest(s,r);">Go</button>
</body>
</html>

When I open the popup, select the first input field and then press the tab key, the input field loses focus but the second one does not gain focus.

If I then select the first one again and press tab once more, the second field gains focus. Pressing again makes the button gain focus and pressing a third time makes the first field gain focus once more.

Does anyone know why the first tab key press would not work?

See Chrome bug report here: http://code.google.com/p/chromium/issues/detail?id=122352

EDIT: Fix is currently implemented in Canary build 26.0.1408.1 (Official Build 181614) at the time of this edit.

This appears to be working in Chrome Version 32.0.1700.76 m.

I have never seen it working properly for my TxtPad extension, but today it worked after the chrome update.

Hope it remains like that now.
