[css-text-decor] text-decoration level 4 refers to a non-existent value of text-underline-position

[jfkthame]

In the description of the text-underline-offset property at https://www.w3.org/TR/css-text-decor-4/#underline-offset, in the table describing the initial position of the underline, there is a reference to an over value of text-underline-position.

However, where text-underline-position is defined at https://www.w3.org/TR/css-text-decor-3/#text-underline-position-property, there is no such value; it lists only auto | [ under || [ left | right ] ]. So over doesn't exist (and left and right are unaccounted-for in the table mentioned above).
