Steps to reproduce:

Open website 'https://www.jysk.ee'
Open Task Manager and leave browser idle
Observe doubleclick.net process memory usage and subframe count

Actual results:

Memory usage and subframe count is constantly rising with each minute
After some hours it reached into several gigabytes filling up all of my memory

Reproduces in safe mode but NOT in private mode.
Tested with 2 win10 PC-s and with both stable and dev versions of firefox.

Expected results:

No such memory wasting.

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: ImageLib' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I can reproduce an increasing number of subframes in about:processes, but I can also reproduce the same thing in Chrome using chrome://process-internals/#web-contents

So I think this is the website.

I can also confirm that MS Edge has similar behaviour.
Initially I compared with Brave or Vivaldi but forgot that they have built-in ad blocking which prevents it from happening.
