Hi @alihassan143,

Thank you for your interest in enhancing the library and for taking the time to submit a solution. We sincerely appreciate your effort in creating the pull request.

While we value your contribution, it is essential to validate this behavior across all potential scenarios before considering its inclusion at the source level. This process involves comprehensive planning, rigorous testing, and an in-depth design review.

As this improvement is already being tracked through an existing feature request, we are not currently accepting direct open-source contributions. We encourage you to share your suggestions through the Feature Request (FR) system, where your feedback will be reviewed during the planning and implementation phases. Please note that we are unable to commit to a specific timeline at this stage.

Nevertheless, your feedback and suggestions are highly valued, and we encourage you to continue sharing ideas through our official support channels.
Thank you for your understanding and continued support.
