[2.1.0] HTML minification problem with php tag with a comment and no space at the end

[hostep]

Steps to reproduce

1. Install Magento 2.1.0 using composer
2. Create a theme and a template file which contains this:

<?php //if ($showDescription):?>
    <div class="product description product-item-description">
        <?php /* @escapeNotVerified */ echo $_helper->productAttribute($_product, $_product->getShortDescription(), 'short_description') ?>
    </div>
<?php //endif; ?>

1. Turn on html minification in the backend

Expected result

1. Page is rendered properly without errors

Actual result

1. Error message appears: Parse error: syntax error, unexpected '<'.

The minified php/html file was turned into:

<?php <div class="product description product-item-description"><?php /* @escapeNotVerified */ echo $_helper->productAttribute($_product, $_product->getShortDescription(), 'short_description') ?></div><?php ?>

Temporary solution

Add a space at the end and it works again, like this:

<?php //if ($showDescription): ?>

Any updates on this?

@guz-anton, @okorshenko, @piotrekkaminski: since you guys were involved in another html minification issue, I'm including you in this conversation.

Hi @hostep ,
We are going to find solution under MAGETWO-55356.

Experienced a similar issue when I installed https://github.com/algolia/algoliasearch-magento-2.

Except the problem line in my case was this line: https://github.com/algolia/algoliasearch-magento-2/blob/master/view/frontend/templates/internals/commonjs.phtml#L41

When html minification is turned on that line looks like
if ($path != '') { $path .= ' }

But I'd expect it to look like
if ($path != '') { $path .= ' /// '; }

Here's a gist of the entire file: https://gist.github.com/m0zziter/b7c2f00afd3684e0642060d19617ab2f

This issue hasn't been closed yet and it doesn't seem like there has been a fix to the Minify HTML problem. @guz-anton @okorshenko @piotrekkaminski is there any update on if this issue has been fixed any of the 2.1 release? Thanks.

Does anyone has a solution?

[hostep]

Yes: add a space at the end, like I mention in my initial post under 'temporary solution' ;)

@hostep maybe that is the best way now,but my project is a secondary development, how can I find all of the End tag :'?>' and add a space... minification library is vendor/magento/framework/View/Template/Html/Minifier.php
right? can I rewrite it?
