yes. the "Active Threads" page does not handle the pages the same as the post display pages.
In 7.5.x it would display posts with broken html, would would destroy the entire page, due to the lack of truncated html close tags.
In 7.6.0 it would display pages with pure text and zero formatting. The HTML would be completely stripped.
In 7.6.1 it displays the pages as they were posted and as intended, except long lines are not wrapped like the display is within the post page.
7.6.2 will have that all sorted out.
Thanks for reporting this bug related only to the "Active Threads" list page.
