Suggested merge commit message (convention)
Fix: Handle refresh token when editor destroyed during token fetching. Closes #17462.
Additional information
The issue was caused by the race condition when token fetching request is initialized, editor is destroyed in the meantime and then the request rejects, reinitiating the token refresh logic.
I added
Token._isDestroyed
property to abort all further refresh action when token is already destroyed.
