In the Plugin Framework, plugins run inside a sandboxed <iframe> for security. By default, the sandbox does not include the allow-popups permission.

Some useful links:

• https://jackhenry.dev/open-api-docs/plugins/architecture/userinterface/

• https://jackhenry.dev/open-api-docs/plugins/guides/designinganddevelopingplugins/

• https://banno.github.io/open-api-docs/plugins/architecture/restrictions/#opening-new-windows

If a link is working as expected in another plugin, opening a new tab, they are likely using the Plugin Bridge.
