Element Click fails on a <tr> with an even number of <td>'s

I'm not certain whether this is actually a WebDriver bug or a table bug. In any case when you click on the space between two 's in a events bound to the won't fire. This comes up as a regression because in JWP implementation it appears to use a script-based click which will fire the event. I've supplied a simple example which fails in all browsers with an actual mouse click and in Firefox/Edge with WebDriver. I know our version of click does do actual hit testing so we're as close to an actual user click as possible.

Start by reproducing the CodePen example and compare an actual mouse click with WebDriver's click behavior across the browsers mentioned. Determine whether the failure belongs to table event handling or WebDriver hit testing, then document the minimal reproducible behavior and the expected result.
