However, this is not currently the case for many situations. + + For CSS properties we have bug 545282 - In animations involving 'inherit' + / 'currentColor', changes to inherited value / 'color' don't show up in + animated value immediately + + For SVG lengths we have bug 508206 - Relative units used in + animation don't update immediately + + (There are a few of todo_is's in the following tests so that if those bugs + are ever resolved we'll know to update this test case accordingly.) + + So in between (3) and (4) we force a sample. This is currently done by + calling SVGSVGElement.setCurrentTime with the same current time which has the + side effect of forcing a sample. + + What we *are* testing is that we're not too zealous with caching animation + values whilst in the frozen state.
