Expectation for the aria-colcount attribute: convey a column count when total column count is unknown

This expectation is from the aria-colcount attribute feature.

Rationale:

Screen readers should not attempt to calculate the column count when it is unknown

Strength of this expectation for different types of assistive technologies:

Screen Readers: MUST NOT
Voice Control: NA

Grading method:

Just one of the listed commands must pass for the expectation to pass.

Notes:

ARIA 1.1 spec: "If the total number of columns is unknown, authors MUST set the value of aria-colcount to -1 to indicate that the value should not be calculated by the user agent."
