After r244195, the Web Inspector frontend doesn't stop updating the current time marker until after it receives all of the corresponding `*.trackingComplete` events. This means that sometimes, the current time marker can move far past the time at which the stop was requested, such as if there's a blocking script (e.g. <https://wkwebviewtest.surge.sh>). We should indicate where the stop was requested, as that is often right after a particular issue is reproduced during a timeline recording (rather than have the user try to figure out (or worse, guess) where they stopped).
It's still useful to have the current time marker continue updating, as we should show all the information we have about captured things, such as blocking scripts.
