UI sequence on main:
tab a selected 12-hour; tab b disabled word wrap; reload tab a.
observed: System default; persisted timestampFormat=locale, wordWrap=false.

same UI sequence on exact PR head:

after reloading tab a: 12-hour; persisted timestampFormat=12-hour, wordWrap=false.
reset from tab b: both tabs show System default.
reverse direction: tab b selected 24-hour; tab a enabled word wrap; reload tab b.
observed: 24-hour; persisted timestampFormat=24-hour, wordWrap=true.
