我创建了一个Chrome扩展，其中包含以下HTML标记的弹出窗口：
< 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>搜索< / label>< input name =searchid =search>< / input> < label for =replace>替换为< / label>< input name =replaceid =replace>< / input> < button onclick =var s = document.getElementById（'search'）.value; var r = document.getElementById（'replace'）.value; sendRequest（s，r）;> Go< /按钮> < / body> < / html>当我打开弹出窗口时，选择第一个输入字段，然后按Tab键，输入字段如果我再次选择第一个并再次按下标签，则第二个领域将获得焦点。再次按下按钮增益焦点，第三次按第一次让焦点再次聚焦。
有谁知道为什么第一个按键不起作用？ / p>

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?

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