[css-align] Should last-baseline's fallback alignment be safe or unsafe? (original) (raw)

The "fallback alignment" for last-baseline alignment is specified as "end". However, should this be "safe" or "unsafe"?

There are two ways we use the fallback alignment:

• If the item requests baseline alignment, but it's not in a context that allows it, we use the fallback alignment instead. In this case, "safe end" is probably best, as it doesn't hide any content.
• After we align all the baselines, we then use the fallback alignment to align the group as a whole within the shared alignment context. In this case, "safe end" is again probably best.
