Missing scrollbars on timeline

[Dorian-Grim]

Description

Scrollbars in timeline are not shown. The bottom one is on the bottom so the user has to scroll all the way down to see it. While the right scrollbar is completely absent. Example: https://uwu-logs.xyz/reports/24-06-27--21-06--Warriturra--Unknown/casts/Mikey/?boss=instructor-razuvious&mode=25N&s=9086&f=9180&attempt=0

Proposed solution in #8

• To fix the bottom scroll bar I did a did a 180 degree X rotation on parent, then another 180 on X for child. This correctly places the bottom scroll bar on top.
• For the right scroll bar I did a direction change from the default ltr to rtl on the parent, then on each child resetting the direction back to ltr.

@Ridepad merging with the pr #8 will implement the demo but also implement solution to issue #13
