Is this on master? If so, it's in core ;)

@01tonythomas: Correct me if I'm wrong.

Changing this would require either increasing the height of all multiline text fields in ApiSandbox, or adding yet another ApiBase::PARAM_* constant and setting it in various places.

Most browsers these days[1] make textareas resizeable by default, which seems like an all-around better solution.

[1]: I can't quickly find figures for that specifically, but according to https://caniuse.com/#feat=css-resize 76.38% support the related CSS [[https://www.w3.org/TR/css-ui-3/#resize|resize property]]. It's possible that some don't apply resize: both to textareas by default, although various pages online say Firefox, Chrome, and Safari all do.

If you are interested in submitting a fix, you should probably follow https://www.mediawiki.org/wiki/Gerrit/Tutorial and produce a patch to mediawki-core I guess. A good first step would be to reproduce the same in your latest development environment.

Thank you
