Some baseline exports are context-sensitive. One example: In line-layout scenario, the last baseline of a scroll container is always the margin-end. In other (e.g. flex, grid) scenarios, it's the border-box clamped offset to the last line in the container. This enables the required 3 different behaviours for `inline-block` scroll containers for 3 different `baseline-source` values: - `auto`: Last baseline, margin-end - `first`: Border-box clamped offset to the first line - `last`: Border-box clamped offset to the last line Differential Revision: https://phabricator.services.mozilla.com/D173886
