I've run into an odd issue where none of the back-end tabs are displaying in Chrome. This includes pages like Global Config, New Article, and New User. When I turn on System debug, the tabs display. If I turn it off, they disappear. This is only happening in Chrome and Edge, not in Firefox. Everything was working previously. Has anyone seen something similar before? There is nothing in the browser error console that points at a potential issue. I've combed through the site error logs and nothing is jumping out as a cause of the problem, either.
Screenshots below depict the Add New Article screen with debug mode turned off, and then turned on, in the Chrome browser.
