Image dimensions not showing on image attachment page after updating to 5.6

Hi everybody!
I’m having an issue just after updating to WordPress 5.6.
I’m using TwentyTwelve theme and after updating to WordPress 5.6, the image dimensions data is not showing on the “image.php” (the attachment page). It just show “x” instead of “1200×800”.
Note that you can check this bug (not sure if it’s a bug but the issue starts to happen after updating to 5.6) even with the last TwentyTwelve theme version.
Seems it’s not loading well the %4$s × %5$s part on the template (image.php).
Could you help me with this? Thank you very much! 🙂
