Amaya 9.55 WinXP bug: apply class tool does not add some classes

Hi,

Both Amaya 9.55-3 WinXP and Amaya 9.99-1 WinXP do not add a class to the 
"Apply class" tool window if the name of the new class is part of the 
name of an already defined class (thus is, if the name of the new class 
is a substring of an already defined class).

Steps to reproduce a correct behaviour:
1. Create the following CSS file
    p.test {
      color: red;
    }
    p.testing {
      color: blue;
    }
2. Save the CSS file
3. The .test and .testing classes are shown in the "Apply class" tool window

Steps to reproduce a wrong behaviour:
1. Create the following CSS file
    p.testing {
      color: red;
    }
    p.test {
      color: blue;
    }
2. Save the CSS file
3. Only the .testing class is shown in the "Apply class" tool window.
