Comment 11 for bug 1797007

I should have included in my last comment that as a test I just hard-coded cellOverflowed() to always return true and that basically brought things back to pre - bug #1794176 speeds, but with the fixes for blank rows. (The Performance tab showed far less time in Layout and $digest was only ~160ms for the first checkin and ~280 for the second. I don't think having tooltips for values narrower than the column is so bad a tradeoff (and can be seen in other applications here and there).

Does anyone see an issue with that solution? (Other than the obvious "just throw the check away if it only ever returns true")
