On a specific confluence page, simply pressing CTRL highlights the entire page

[Steve Ziuchkovski]

I have a wiki page on out Confluence server. After I published a change, whenever I press either CTRL keys, the test on the entire page highlights. This only happens in Chrome (not in Firefox), and only happens on a single page. This makes it difficult to copy text...

Any ideas? 6.15.4

Same here on 6.13.8 (also on Chrome and not in Firefox).

We have some tables and Drawio diagrams on that page if it helps.
