How to reproduce

  1. Visit this YouTube video:
  2. Observe the initial block counter (Seen: 21, 31, 40).
  3. Navigate along the video timeline 5-10 times.
  4. Observe the block counter increases by 10-20-ish (varies) each jump on the timeline.
  5. Observe that after Step 4 (and having jumped near the end of the video), the block counter displays hundreds of blocked adverts.
  6. Repeat the same above using this video:
  7. Observe the counter doesn't increase anywhere near the same amount (or sometimes at all) when jumping through the video.

Observed behaviour

Every time certain videos are jumped/scrubbed the block counter is increased by what seems to be an excessive count.

Expected behaviour

The counter to increase with the actual number of blocked adverts.

In the first video above, adverts are present in the video timeline (yellow dashes) when ABP is disabled. In the second there are no "in-timeline" adverts. That explains some of the difference in count between the two, but are there really 10-20+ adverts being blocked every jump in the first video? Is it counting all the adverts in the timeline each jump?

I noticed this after noticing #442. The explanation given in that ticket makes sense and could apply here. Just the count seems excessive. (I still need to/should try the same with an older build).
