Bug 1497153 [wpt PR 13416] - [css-properties-values-api] Include initial values in computedStyleMap., a=testonly Automatic update from web-platform-tests[css-properties-values-api] Include initial values in computedStyleMap. Registered properties with initial values are currently missing from the computedStyleMap, because such properties are not explicitly stored on individual computed styles. To fix this, do an extra pass over the PropertyRegistrations to "fill in blanks" with initial values.
