Automatic update from web-platform-tests script: Clamp table spans according to the HTML specification Previously, spans were partially clamped during layout, but this means that accessing and setting these properties via script wouldn't behave according to the HTML specification. In addition, the value wasn't floored in layout, so could lead to panics. This change improves clamping and moves it to script. Fixes #36699.
