Posted by developer:

This issue applies to the legacy MySQL Workbench 8.x implementation that is no longer supported or maintained.
MySQL Workbench 26.7 is a complete rewrite using a new technology stack and does not use the affected legacy implementation.
Therefore, this issue is not applicable to the current MySQL Workbench product and as such is closed.
