Seeking in a replay causes a miss on a 0 miss score

See original GitHub issue

Describe the bug: Watching a replay of a score I set on osu!lazer, there will always be a miss on the same slider, if you seek through the replay.

The score was set on this beatmap: https://osu.ppy.sh/beatmapsets/471285#osu/1007403

And this is the exported replay file (in zip format for github upload): Sinamer playing Lindsey Stirling - Master of Tides (LunaSaika) [Violin Dance].zip

So, the miss is in a slider head. Without the classic mod, the slider head position is moved to follow the slider ball: https://github.com/ppy/osu/blob/0dcdad98397453b439cab67421e29ecb3ca13f00/osu.Game.Rulesets.Osu/Objects/Drawables/DrawableSliderHead.cs#L81

A hit circle uses the IsHovered property to check the hit when a button is pressed:

The issue is this IsHovered is only updated in InputManager’s update, using the Position from the previous frame. The issue occurs on fast forward due to the different frame rate. In theory, the same issue can happen by using different fps limiter settings. Related (?): #4288.

I’m pretty sure this isn’t a new issue and has been around for a while, but I can’t actually find an open issue tracking this.
