Doc-block suppress for UnusedForeachValue

<?php

/** @var array<string, int> */
$data = [];

/** @psalm-suppress UnusedForeachValue */
foreach ($data as $k => $v) {
    echo $k;
}

I would expect that error on unused foreach value is suppressed, but getting the following:

Psalm output (using commit 9d68e2e): 

INFO: UnusedForeachValue - 7:25 - $v is never referenced or the value is not used
 
Psalm detected 1 fixable issue(s)

also it's marked as fixable, but fixing is not working as well.

I found these snippets:

<?php

/** @var array<string, int> */
$data = [];

/** @psalm-suppress UnusedForeachValue */
foreach ($data as $k => $v) {
    echo $k;
}

Psalm output (using commit 9d68e2e):

INFO: UnusedForeachValue - 7:25 - $v is never referenced or the value is not used

The fixable flag should be fixed by #6238. The fact that UnusedVariable issues can't be suppressed is by design. It was already suggested as a change in #5537 so this issue can be closed when #6238 is merged
