Instantiating a dialog with a component that contains a regular HTML
<button>
element causes a DOM node memory leak.What is the expected behavior?
No memory leak
What is the current behavior?
Memory leak
What are the steps to reproduce?
https://stackblitz.com/edit/angular-material2-issue-dhmjle?file=app/app.module.ts
1) Open Chrome performance monitor 2) Click Memory > Garbage collect 3) Note the initial DOM node count (around 53) 4) Click the "No leaks on div" button a few times and watch the DOM node count climb 5) Close any open dialogs and press the "Garbage collect" button again 6) Watch the DOM node count decrease to around the initial value (plus some "sticky" dialog nodes that intentionally stick around) 7) Click the "Leaks on button" button a few times and watch the DOM node count climb 8) Close any open dialogs and press the "Garbage collect" button 9) Note that the DOM node count does not decrease to the initial value
