AddQuicktag can’t setting

In ver2.6.0, new tags cannot be set.
When I press the setting button, the display check of the existing tag is unchecked.
The export is not registered either.

The display name of the new tag disappears. Overwrite can be registered with, but it cannot be used because the display check is cleared.

I can use it by downgrading to ver2.5.3.

I have seen similar error on many of my sites.

A similar error was confirmed with a new WP that had a clean installation.
Similar error were confirmed in WP downgrade ver5.6

The WP ver I’m using is 5.7.1-ja
