Layout function should return an indication that it was unable to layout an element
We can use the
layout function to know if the content has sufficient break points to prevent content from overflowing the fragmentainer.
In other words, if the
layout returns an "error" because content is overflowing then we can use this information to drop rules (for instance,
break-before: avoid or
break-inside:avoid) in order to find additional breakpoints.
Currently, the function returns
undefined or a
BreakToken. The chunker is also using a
breakToken mutable variable that can equal to any one of these values:
undefined it's unclear if was because the function couldn't layout an element.
We could probably return a
LayoutResult object that might contain a
BreakToken and/or an error (or a list of elements overflowing from the fragmentainer).
We could also throw an exception, catch it and decide if we want to proceed or if we want to abort.
