Nit - an unnecessary synchronous layout update.

This is unnecessary after https://trac.webkit.org/changeset/227664 and https://trac.webkit.org/changeset/226823.

m_selectionRevealIntent is never reset. m_pendingSelectionUpdate bit can get also set by FrameSelection::setNeedsSelectionUpdate in which case we presumably use whatever intent was set earlier. This doesn't seem right.

That's okay. What's not okay is that we're not resetting m_selectionRevealMode in some cases. We should probably fix that in a separate patch since that's a pre-existing bug.

Let's track that in the bug 182378.

This change has caused LayoutTest fast/dom/adopt-node-crash-2.html to become a flaky failure on High Sierra Release WK2 and Sierra Release WK2:
https://build.webkit.org/results/Apple%20Sierra%20Release%20WK2%20(Tests)/r228225%20(7494)/results.html

I am able to reproduce the failure with a build of r227984 with the following:
run-webkit-tests fast/dom/adopt-node-crash-2.html -fg --iter 100 --exit-after-n-failures 1

I cannot reproduce with a build of r227982.

I think this is a bug in the test. Tracking that in https://bugs.webkit.org/show_bug.cgi?id=182589.
