How to highlight pinned tab in Chromium via javascript

Question

There is a feature in Chrome - you can right-click on a tab and select "Pin Tab", then tab is moved to the left corner and looks like an icon with text.

So there is the question: how can I highlight this tab? Maybe there is some API?

For example, gmail can highlight this tab when new mail message is come.

Thank you.

You can't blink the tab, just the tab title:

<script>
function blinkTitle() {
 if(!window.oldtitle) window.oldtitle = document.title;
 if(document.title == ' ') {
  document.title = window.oldtitle;
 } else {
  document.title = ' ';
 }
}
function startBlink() {
 window.blinkinterval = setInterval(blinkTitle,200);
}
onload = function() {
 document.onblur = function() {
  setTimeout(startBlink,2000);
 }
 document.onfocus = function() {
  clearInterval(window.blinkinterval);
  document.title = window.oldtitle;
 }
}
</script>
