 Sometimes bugs reported to us are actually caused by bugs in the browser(s) themselves, not bugs in Bootstrap per se.
 When feasible, we aim to report such upstream bugs to the relevant browser vendor(s), and then list them on our [Wall of Browser Bugs](https://getbootstrap.com/browser-bugs/) and [document them in MDN](https://developer.mozilla.org/en-US/docs/Web).
