Backspacing in a text entry field on http://jisho.org makes the browser go back, does nothing if URL marked as exception

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Go to http://jisho.org
2. Enter something in a text entry field and hit backspace
3. Notice the browser goes back in history and not erase entered text
4. Open up the extensions list and enter the options of Backspace As 
Back/Forward For Linux
5. Add jisho.org as an exception to the extension
6. Return to jisho.org, enter something in a text field and hit backspace

What is the expected output? What do you see instead?
At (3) the browser should just erase entered text when backspacing. Instead 
the browser goes back in history despite a text entry field having focus.
At (6) it does /nothing/. The browser doesn't go back, nor is any text 
erased. To erase text you have to move the caret back and use the delete 
key instead.

What version of the product are you using? On what operating system?
Extension version: 0.49.1
Chromium: 5.0.386.0~svn20100423r45407-0ubuntu1~ucd3
OS: Linux, Kubuntu lucid with packages up-to-date at 2010-04-25

Please provide any additional information below.
Perhaps this is some quirk of how said site is written, but I figured that 
entering it as an exception in the extension options would work around 
this.

Added input field type "search" to the legal textfield values. Update the 
extension 
and it should work as expected. Please remember to remove the blacklist 
exception :)

If it won't work please reopen this issue.
