Osu: If I modify my DT Speed it doesn't show in replay.

[porkiedev]

(This is a hybrid of a bug report and feature request, not sure how it was implemented so I'm not sure if it's 100% a bug or not.)

Describe the bug: In osu!lazer, you can enable DT and change the speed (I like playing on half DT meaning 1.25 speed) and my issue is that when I finish a map with 1.25 speed and look at the replay, it shows the replay as if it were at normal DT speed (1.50)

Screenshots or videos showing the encountered issue:
(I have a widescreen monitor so it's slightly stretched, sorry.)
I first played the map on DT 1.25 then watched my replay, that way you can see how to goes back to normal DT.
