[Plugin: Google Syntax Highlighter for WordPress] Invalid CSS

This is in regards to the Google Syntax Highlighter for WordPress Plugin version 1.5.1.

I receive the following: “Warning: Unknown property ‘text-align1’. Declaration dropped.” This occurs on line 113 in the source file: /wp-content/plugins/google-syntax-highlighter/Styles/SyntaxHighlighter.css

Line 113 reads as follows:

text-align1: right;


Unless this was intentional, I am assuming it should then be:

text-align: right;
