[Chromium] Half of the '-' is visible when there is a scrollbar in the popup

[my-password-is-password]

When the popup has a scrollbar you only see half of the '-'.

Here's a popup with no scrollbar. You can see the full '-'.

Haven't checked if this happens in Firefox.

Doh, stable Chrome works perfectly. Sorry
