We want to know if the option is selected in `EnumSettingsOptionInfo` so we can style "invalid" statements accordingly.
> Why do we need to style "invalid" statements accordingly?
Here's a video demonstrating what happens otherwise:
{F56435}
Basically, the color that the option is highlighted with matches the color of "invalid" statements. That means that when an option is selected, the "invalid" statements are pretty much invisible.
We were previously solving this problem with a CSS selector that looked like:
```
div.optionContainerSelected div.optionInfoInvalid {
```
However, that approach broke when I was splitting the styles into separate files. It's a little brittle and depends on a particular nesting of divs that are a side effect of an option being selected.
Instead, with the current approach we directly check whether an option is selected and style "invalid" statements based on that accordingly.
Here's a demonstration with the "selected" color set to red for illustration purposes:
{F56436}
