Subject: [PATCH] QTest::qWaitFor(., int): restore lost Qt::PreciseTimer'ness
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Before the qWaitFor() port from int to QDeadlineTimer, the
implementation constructed a QDeadlineTimer internally, passing int
timeout and Qt::PreciseTimer. The int overload that was retained for
source-compatibility, however, constructs the QDeadlineTimer without
the PreciseTimer flag, which is a behavior change.

Restore the Qt 6.6 behavior and pass Qt::PreciseTimer.

Amends fa296ee1dcf4c16fb6f242cf08949485e499fec3.

Pick-to: 6.7.0
