WEBTOON Ads Inflating My iPhone Screen Time?

[u/rosa_diaz23]

Has anyone else experienced this on iOS?
I suspect WEBTOON's ads are causing imasdk.googleapis.com to accumulate Screen Time. Every time I open an episode, an ad appears. I close the episode to make the ad disappear, but the domain still seems to count the time.

Here’s what I noticed:

WEBTOON — 1h 45m;
imasdk.googleapis.com — 1h 45m.

WEBTOON — 3h 13m;
imasdk.googleapis.com — 3h 23m.

I also noticed that closing the episode doesn't stop the domain's time from accumulating. It seems to be contributing to my actual daily Screen Time total.
Could this be related to WEBTOON's ad SDK, or is iOS misattributing the activity?
Has anyone found a way to fix this without uninstalling WEBTOON or disabling Screen Time?
I've attached screenshots of both days.
