[css-anchor-position-1] position-area: self keyword inconsistency

[tuankiet65]

The syntax definition of position-area says the self version of block-start, block-end, inline-start, inline-end is the same keyword but with the self- prefix (so self-block-start, self-block-end, ...).

However in the section explaining what the keywords mean, self is placed in the middle of the keyword instead of (block-self-start, block-self-end, ...)

So which of these is the correct convention to use?

This also leads to a relevant issue - in the syntax definition, we both have self- as the prefix (e.g: self-block-start, self-inline-start), and self- in the middle (e.g: x-self-start). Should we fix the syntax to be consistent where self- could be in the keyword?

For some perspective, Chome implements it as exactly as the syntax definition says, and the WPT tests reflect it.
