Sometimes I get pleasantly surprised, but generally speaking the internal incentives are skewed against, the primary focus is whatever the roadmap is followed by tickets from paying clients, public bugs generally have a very low hit ratio so they're unrewarding, unless you manage to snipe one of the company's employees (either nerd-snipe or interest / shock them enough to raise the issue internally) it's like playing the lottery.
What works to some degree are dedicated maintenance teams providing development support. If their main task is fixing bugs and they are evaluated on this basis, support tickets reporting real bugs have a good chance to receive the required attention.
However, there is always the temptation for management to redirect resources from those teams. But at least in the B2B area costly customer escalations can remind management of the importance of good maintenance.
Despite Google partly losing its marbles recently, reporting bugs to Chromium still works very well.
