Continuous indentation wrapped smarty code in pre tags or vice versa

[Namstel]

Describe the bug
When I write smarty code within a foreach loop within HTML pre tags, running the code formatter keeps inserting tabs/spaces when triggered.

To Reproduce
Take this code:

<pre>
  {$array = ["a thing"]}
  {foreach $array as $item}
    {$item}
  {/foreach}
</pre>

Now trigger the Format Document command several time and you will see it will keep indenting the line with {$item}.

Expected behavior
I expect it to indent correctly once (if needed), and then stop.

Context (please complete the following information):

• Version 1.9.0

I found out that it isn't just happening with the foreach loop, but whenever there's a piece of smarty code wrapped, so also with an if statement.

{$array = ["a thing"]}
<pre>
{if $item === "a thing"}
  {$item}
{/if}
</pre>

{if $item === "a thing"}
  <pre>
    {$item}
  </pre>
{/if}

It only seems to happen with the pre tags.
