Describe the bug

This one took some serious debugging to isolate, it wasn't obvious at all. So I have a set of BTabs within a BForm, and whenever I click on one of the tabs, the entire page reloads. No warnings, error messages, nothing. Just a hard reload. I think that what's actually happening is, clicking on the BTab (a button element) is actually causing the form to submit, but since there's no action specified, it just "submits" to the current page, causing a reload. I can successfully work around this by adding @submit.prevent to the BForm. I suspect that simply adding type="button" to the BTab buttons would fix this issue.

Reproduction

Used Package Manager

npm

Edit: Confirmed that by adding :title-link-attrs="{ type: 'button' }" to all BTabs it does fix this issue.
