Error message when using shortcut keys with highlight-words extension

[schlace]

@rsbondi I am using “highlight-words”, which is mostly working well. It can highlight specific words and allow me to use the mouse to click the left and right arrows in the sidebar to jump to the previous or next match. However, when I use the shortcut keys to do the same operation, I get an error message in the bottom right corner: “Cannot read properties of undefined (reading ‘highlight’)”. Could you please help me analyze why this happens and how to fix it?
