Target is sometimes not shown fully on panel captcha

Description

Target is sometimes not shown fully on panel captcha. Probably similar to #2956 but device DPI settings were 100%.

Steps to Reproduce

1. Set locale to Japan and device DPI to 100%(default)
2. Set env to staging to trigger grant
3. Open panel, sometimes one of the target is not fully shown due to extra padding on message for other locales

Actual result:

Expected result:

Should always show the targets fully

Reproduces how often:

Easy but needs a few retries of failed attempts
