Actual

This occurs when the value of the property can be entirely found in the name of that property.  For example, "border-collapse: collapse;" will highlight the "border-collapse" and then just the "collapse" because the code is trying to find the first index of the value (which is "collapse") and that happens to be inside the name.

Thanks to @Nikita for the gif.

Nit: text.indexOf(":") used twice here, it should be pulled into a variable.

What if this returns -1?

You can do this without doing a substring. If you make the regex, then set regex.lastIndex = colonIndex, it will only search after that.

On the next line, it checks if colonIndex >= 0 and if not then set the start to 0 since the entire string should be matched.
