Question

我正在玩一个Firefox扩展程序：

1）当我按create or replace view task_statistics as select user , count(distinct id) as total_completed_tasks , avg(completion_time) as avg_completion_time , avg(length) as avg_task_length , avg(difficulty) as avg_difficulty , avg(cost) as avg_cost from task group by user;

时，显示扩展名弹出页面

2）弹出页面侦听Ctrl+Space事件。根据键的不同，在关闭弹出窗口之前，会将新网站加载到新的浏览器选项卡中。

问题

当我按keydown时，弹出窗口将按预期方式显示。但是，有时看起来好像弹出窗口不在焦点上，这意味着将错过所有按键事件。当我在弹出窗口中单击以使其重新聚焦时，将按需捕获按键事件。

如果我通过单击扩展程序的按钮显示弹出窗口，则不会出现这种间歇性行为。

我不确定这是否是Firefox问题。有没有人在解决此问题之前和/或知道解决方法？

编辑：经过进一步调查，间歇性行为的发生主要是在事件处理程序加载后立即快速按下Ctrl+Space并打开一个新标签页，该标签页包含Ctrl+Space或https://www.youtube.com之类的网站。事件处理程序加载Google或StackOverflow时似乎没有发生。也许媒体重磅网站正在以某种方式窃取焦点？
