Window.open make memory leak?

I added button to open meeting in new tab then I see used memory goes up any suggestions ?

window.open will allow you to communicate with the window you just opened, so there is a communications channel between them, not a leak.

If wait more time this tabs will be crash, I am not sure this is normal behavior.

Can you try this? window.open(URL, '_blank', 'noopener')

Thanks
'popup=1,noopener,noreferrer' helped
