Tag to disable counting of words and reading time

I have an article with many text information that should be just seen, and not read. This information is hidden under the clickable <details> section. But unfortunately, all this information counts as readable and vastly affects article reading time. I suggest adding an ability to remove some sections from words counting and reading time counting.

Possible UI for this feature:

text that matters

<!-- disable_counting -->
some additional information
<!-- enable_counting -->

again text that matters
