Sorry about the delay on this bug, but it's unfortunately a difficult problem that doesn't always occur for everybody, and therefore is hard to investigate. I'm trying to reproduce the issue now, but can't. Comment 0, comment 8 and comment 9 mention using a macbook, so that's what I'm doing too. I'm testing this with Firefox 64 and 65. Apart from Martin in comment 4 (and bug 1487284 which Julian linked), there's no mention of RDM. So I'm not quite sure what other scenario to test. I've tested exactly like Martin said, and I've refreshed the page many time. I've not seen the problem myself so far. @aequalsb: by any chance, do you have RDM (Responsive Design Mode) open when it happens? @repertor: same question to you? Also, to both of you, whenever it happens, are there errors in the browser console (cmd+shift+J)? If so could you please paste them here?
