Lexically replace variable does not work on outer variable

[szabgab]

my $x = 23;

{
	my $x = 42;
	print $x;
}

print $x;

Put the cursor between $ and x in the last $x, right-click and lexically replace by $z. All 4 occurances of $x will be replaced.

Actually same happens when I mark the second $x declaration (within the block)
it replaces all 4 occurances

[szabgab]

The last problem is that if I mark the first occurrence of $x it will say it cannot find the declaration of the variable.
