UI study-view regressions in 0.17

[youurayy]

Description

1. the "Timeline" view doesn't fill the width of its cell anymore.
2. the "Study User Attributes" view now defaults to 50 rows limit (before it was 5), pushing the "Intermediate values" off the view even on long pages. Also the minimum changed from 5 to 10.

Ideally the "Study User Attributes" would default to 5 again, and/or configurable in Settings, and/or remembering in a cookie or local storage.

Thanks!

How to Reproduce

1. Optuna's objective function is '...'.

Another solution would be swapping the "Study User Attributes" view with the "Intermediate Values" view, perhaps even making the "Study User Attributes" that the full with as the last view at the bottom.
