Display Strike line on verifyElementVisibleInViewport in script mode

When I use Verify verifyElementVisibleInViewport keyword in katalon then it is displayed strike line on that keyword name in script mode
any idea on this?
check screenshot.

it is deprecated, but I think you can still use the new keyword.

The description of the new keyword is also noted as deprecated … but it makes no sense ! So I think you can use it.
