I am trying to make link to another site open in the same tab. but it doesn't work

<a target="_self" href="https://www.someotherdomain.com/"> click here to go to external site </a>

However if I change the link to that of my website, It works fine.

<a target="_self" href="https://www.mywebsite.com/">click here </a>

Is there a way to force the external link to open in the same tab. like it does with internal links?
