Scrubbing Playback Speed under Geometry Cache in the details panel is too sensitive

Scrubbing Playback Speed is very sensitive and even a small mouse movement will cause playback speed to jump way too much.

This makes it very hard to set it to smaller values and mostly a usability issue

1. Load QAGame in the editor
2. Click Import from the Content Browser
3. Navigate to \Engine\Content\NotForLicensees\QA\Import_Test_Assets\AlembicAssets and select SceneTest.abc, then click Open
4. Change the Import Type to Geometry Cache
5. Click Import
6. Drag the SceneTest geometry cache from the Content Browser into the level
7. Position the camera such that you can see the shapes in the asset (you may need to scale the asset up by a factor of 5)
8. Simulate in the Viewport
9. Select the asset in the level
10. In the Details panel, scroll down to the Geometry Cache section
11. Scrub the Playback Speed field

Result: Playback Speed jumps by ~ 10 for each unit of mouse movement

Expected: Should be much less sensitive and maybe only move ~ .25 per unit of mouse movement
