Per the duration change algorithm [1]
```
4. If new duration is less than highest end time, then
Note :This condition can occur because the coded frame removal algorithm preserves coded frames that start before the start of the removal range.
1. Update new duration to equal highest end time.
Update duration to new duration.
```
However

we set the duration to the value originally passed.
This causes the test `LayoutTests/media/media-source/media-source-play.html` when run in the GPU test, this wasn't an issue when the MockMSE runs in the content process as it always reads the duration from the parent MSE instead which is correct.
