I am using the Advanced CSS/JS Aggregation module to load css once the page has loaded:

<link type="text/css" rel="stylesheet" href="/sites/default/files/advagg_css/css__fQOpwieSv5u9MLUdCJW8AX3ysBkVaiLC0mNO9bCuF8c__FLUdFFsRYhU7NN2T4QA7b0pMyQP1W1hRmVlZ5H2Saxs__sq6B6dIZCxhnK6op34i0_MkLadmDDYLWNc-Y9yWUjsQ.css" media="all" as="style" onload="window.advagg_mod_loadcss = function() {if (window.jQuery) {if (jQuery.isFunction(jQuery.holdReady)){jQuery.holdReady(false);}} else {setTimeout(advagg_mod_loadcss, 100);}};setTimeout(advagg_mod_loadcss, 200);this.onload=null;this.rel='stylesheet'">

The problem is that sometimes only on Microsoft Edge, the stylesheet does not get loaded (I don't see the styles getting applied on my site). Once I reload the page, it works fine. It's hard to replicate because it does not happen all the time and it only happens one time per page.

I don't see any errors in the developer console.

When looking at the Network Tab it shows that it gets the file from cache.

I posted an issue here on Advanced CSS/JS Aggregation issue queue.

I had an older version of Microsoft Edge (14) and I could not reproduce the problem. It looks like it only happens in version 17.

  • This question does not appear to be about Drupal within the scope defined in the help center.
If this question can be reworded to fit the rules in the help center, please edit the question.

  • Is the snippet you posted custom code you've written yourself? Did you already check advaggs issue queue? As that probably is the place where this question belongs to. – leymannx Oct 29 '18 at 20:00

    I'm voting to close this question as off-topic because this sounds like a bug report and should be posted on drupal.org instead. – leymannx Oct 29 '18 at 20:02
  • @leymannx This is not custom code but how advagg works. I did check and posted an issue on Advaggs module but did not get any feedback. – albertski Oct 29 '18 at 20:11
  • Cool, could you include the URL to the issue in your question? – leymannx Oct 29 '18 at 20:23
