Powershell Script Highlighted Inconsistently

I'm using the SyntaxHighlighterCode in several of my wordpress.com posts, and noticed that for longer Powershell scripts (which run without errors) the color coding is not right. One example can be found [here](https://mihai-albert.com/2020/05/31/automatically-recover-zoom-licenses/#powershell-script).

Notice the issues within the function - almost entirely rendered in blue. Also note that in the script's main body, right after Method = 'GET', a significant portion of the text is again blue. However the function's inner code, placed several paragraphs above, renders just fine.
