eBay contact buyer message text disappearing and reappearing as I type - Safari issue
Recently a new behavior cropped up on the eBay seller interface in Safari only, not a problem in other browsers. I have an eBay store. When I try to enter text in a “contact buyer” window, the text disappears as I am typing. If I continue typing, it reappears for a second and then disappears again. It acts as though the text is turning white intermittently, or a white window is coving it intermittently. It is impossible to write a message this way. If I write it in TextEdit and paste it in, it disappears immediately, but if I send the message anyway, and then check my eBay messages sent folder, it was sent correctly. Is this an eBay website/Safari incompatibility? Sending messages to sellers works fine, it's only the “contact buyer” composition window that seems affected. Safari 12.0
