[Investigation] Investigate memory increase when popup is open

[MichaelKohler]

I have noticed that the memory footprint in Chrome increases while the popup is open. In my recorded case (see below) it doesn't grow as much as I had seen before. In one instance earlier this week I saw it grow by almost 20MB before memory got freed again. There is no user action taken, just the popup being open. Without the popup being open, the background script memory is stable.

In theory it could be that this is common behavior for popup implementations in Chrome, however I think it's worth investigating and figuring out why this is and what could be done to avoid that.
