RT at a Glance modification

Hi list,

I notice that under version 3.8.2 the length of the subject adjusts
into the RT at a Glance page, seen the “Quick Search”, “Reminders”,
etc.- moving from side to side depending on ticket subject length.

Is there a way to change this as per 3.6.1 handles? I been looking
through some css but can’t find this.

Many Thanks,
