Code-checker reports HTML-inside-PHP indentation as incorrect, when it is correct

I have been using the code-checker to help upgrade some previously-1.9 code to 2.x, and I have noticed that indentation is sometimes reported as incorrect when it is not (as far as I am aware).

In the below (example) scenario, when breaking out of PHP to add a block of HTML, the codechecker suggests that lines 4 to 10 are incorrectly indented:

01. <?php

02. if (1=1) {

03.     $somevar = true;

04. ?>

05. <div>

06.     <p>

07.         <span>some page content</span>

08.     </p>

09. </div>

10. <?php

11. }

12. ?>

The code-checker identifies line 3 as intented correctly, but then expects the PHP tags and HTML to be similarly indented, which I do not believe should be the case. Example error:

<center>
472: Line indented incorrectly; expected at least 4 spaces, found 0

I don't think that when breaking out of PHP into HTML the indentation should be maintained. Certainly this is not the case from many chunks of code I have seen: HTML maintains its own intentation, sometimes using two spaces instead of four, sometimes using no indentation at all.
