Subject: [PATCH] perf report: setup elide when siwtch to another event in by tab key

From: Changbin Du <changbin.du@...el.com>

When we zoom into a column, that column is elided. But this should apply
to another event browser window after event switch by tab key. We need
setup elide corresponding to new event.
