Multiple sub tables are not correctly processed by the WikiProcessor

[f.rochlitzer@…]

The following table definition isn't processed correctly:

{{{
#!table style="margin: auto"
	{{{#!tr
		{{{#!th style="background: lightgray"
			Head Column1
		}}}
		{{{#!th style="background: lightgray"
			Head Column2
		}}}
	}}}
	{{{#!tr
		{{{#!td
			{{{#!table
				{{{#!tr
					{{{#!th style="background: lightgray"
						Sub head column1
					}}}
					{{{#!th style="background: lightgray"
						Sub head column2
					}}}
				}}}
                                {{{#!tr
					{{{#!td
						Sub column1
					}}}
					{{{#!td
						Sub column2
					}}}
				}}}
			}}}
		}}}
		{{{#!td
			{{{#!table
				{{{#!tr
					{{{#!th style="background: lightgray"
						Sub head column1
					}}}
					{{{#!th style="background: lightgray"
						Sub head column2
					}}}
				}}}
                                {{{#!tr
					{{{#!td
						Sub column1
					}}}
					{{{#!td
						Sub column2
					}}}
				}}}
			}}}
		}}}
	}}}
}}}

I get allways the following error message:
!#tr must contain at most one table

If you remove the table definition in the last column, the code will processed correctly.

Well, yes, this is a known limitation, so marking this as an ER ;-)

Depends on #4431.
