Static content deployment breaking template files in vendor

[kamilszewczyk]

Preconditions

1. Magento 2.2.5

Steps to reproduce

1. A module installed in vendor with a template file with a content
   <script src="//test.js/<?php echo $block->getParam() ?>/<?php echo $block->getParam() ?>"></script><script>runFunction(1, 2);</script>
2. Run setup:static-content:deploy command
3. Check content of the phtml file

Expected result

1. A correct phtml file (not modified)

Actual result

1. Modified and broken phtml file

Changing the <?php echo syntax to <?= fixes the issue but I don't think it's a desired behaviour?

@kamilszewczyk : I assume it only happens when html minification is enabled?
It sounds a bit like #5316 (which should get fixed in 2.2.6), since you also have something which looks a bit like a comment: //test.js (I assume this is just a placeholder for an actual domain name?). Does changing that to https://test.js fixes the issue as well?

[kamilszewczyk]

@hostep
the HTML minification is actually disabled.
The //test.js is a placeholder for the domain name to include with same protocol as the current site.
Changing to https://test.js seems to fix the issue, but so is changing to <?= in the php opening tags.

It does seem very similar to the #5316 I will keep an eye on this issue in 2.2.6

Hello @engcom-backlog-nazar

I have just noticed the same issue occured on other 3rd party module and it was reported here YotpoLtd/magento2-module-yotpo-reviews#18
It seems that the PHP version is also a variable.
I've been testing my code on PHP 7.1.20-1+ubuntu18.04.1+deb.sury.org+1 can you please check reproducing of this error on it?

Hi @kamilszewczyk thank you for you reply, yes i'm will testing this again, but if i'm good remember, I tested with the 7.1.20 php version

Well at least thanks to the yotpo module bug report I know that it's not a isolated case that happened only for me, but is actually encountered by other people
