Gitlab: fix command palette overflow
Created by: lguychard
Fixes #6151
The fix here is to stop applying the popover
class to the popover by default, as in Gitlab styles a .popover
has a max width (while in Sourcegraph styles .command-list
has a fixed width of 24rem).
The Bootstrap popover
class was applied in shared/src/commandPalette/CommandList.tsx
, it wasn't intentionally used to match Gitlab styles.
Since with this fix, the popover class will no longer be applied by default on other code hosts either, I verified that display of the command palette on GitHub and Bitbucket Server was unaffected. No need to check on Phabricator, where we still don't inject the command palette.
