|

// as the base argument takes care of most of the normal mode
|

// functionality, but a second (typically simple) mode is used, which
|
|
// can override the style of text. Both modes get to parse all of the
|
|
// text, but when both assign a non-null style to a piece of code, the
|
|
// overlay wins, unless the combine argument was true and not overridden,
|
|
// or state.overlay.combineTokens was true, in which case the styles are
|
|
// combined.
