Chapter bar should be filling height properly on hover

[rosingrind]

Issue

If you hover any part of video timeline, the timeline bar reacts with raising it's thickness (height). Using SponsorBlock with enabled Show Chapters setting, you don't get the same experience - the custom-colored chapter part of timeline stays static, which introduces sort of visual confusion
