See the image by yourself:


I have Opera 10 and Firefox 3.5 to show you how I don't like the select box in Chrome (4.0.275.0, Chromium) on Linux. You can see the dropdown box is shorter than text input and the button. It creates strange visual distraction, quite annoying. The others two browsers have same tall UI elements, I don't know what's wrong with Chrome.

The HTML code is:
<!doctype html>
<html>
  <head>
    <title>Hello HTML</title>
  </head>
  <body>
    <p>Hello World!</p>
    <input type="text" value="Text Input"/>
    <input type="button" value="Click on me!"/>
    <select>
      <option>This is always shorter and I hate that!</option>
      <option>Option2</option>
    </select>
  </body>
</html>

I don't have any other WebKit-based browser installed, therefore I really don't know if this is Chrome's problem or Webkit's. I hope it will have same visual appearance in further releases. I couldn't find an issue on its list about, but I am also lazy to create one. So give me a link, I will star it.

It's still the same story...
