[css-lists-3] [css-values-5] Potential issue with toggle() and ul in css-lists-3 Appendix A #13753
Description
Hi,
While implementing the toggle() function in my web engine, I believe I found an error in Appendix A: Sample Style Sheet for HTML of the css-lists-3 specification.
The sample stylesheet suggests defining unordered lists as follows:
ul { list-style-type: toggle(disc, circle, square); }However, the initial value of list-style-type is disc.
According to css-values-5 regarding how toggle() is evaluated:
"Then, compare the property’s inherited value with each Cn. For the earliest Cn that matches the inherited value, the computed value of toggle() is Cn+1."
The Issue:
Because the default inherited value is already disc, the toggle() function will match disc (C1) and immediately compute to the next value in the list, which is circle (C2).
This results in a top-level <ul> incorrectly computing to circle instead of the expected disc.
