It is correct that I don't understand why the fact that the DOM of 
  both WebKit and Firefox kicks foreign elements and foreign text 
  out of the <table> container isn't seen as part of the table 
tainting problem. Or why one should try to solve tainting without 
also solve the other problem.

Henri's first example in that thread[1],

	<!doctype html>x<table> x </table>

does in Firefox result in the word "xx" outside the table plus 
whitespace inside the table. In Webkit, the result is two words, 
"x x". And so on. This is result of different whitespace 
treatment, OK. But first and foremost is it a result of the fact 
that they both kick illegal stuff out of <table>.

Opera and IE has the same way of doing table tainting. But then, 
they also do not kick illegal stuff out of the table DOM.

If Firefox and Webkit could get the same behaviour as Opera and IE 
w.r.t. illegal stuff inside <table>, then they would probably also 
solve much of the tainting problem for free.
