Similar to the issues reported in MDL-32298, the <object> tags that Moodle uses to embed LTI External Tools cause erratic behavior in recent versions of Google Chrome.

Clicking on the scrollbar of the embedded content causes the content to scroll erratically – the content will continue to scroll even after the primary mouse button has been released, which essentially renders the browser unusable.

While this issue is technically a Chromium bug, Moodle users are likely to encounter fewer bugs if content is embedded using the considerably more common <iframe> tag.
