Change "Override title" field type from textfield to textarea

If I set up a complex view with multiple contextual filters, I may be using the "Override title" option under the "WHEN THE FILTER VALUE IS IN THE URL OR A DEFAULT IS PROVIDED" section of settings on the contextual filter(s). Right now, this field is type textfield, which means it's limited to 128 characters. The beauty of this field (and many others, like Custom Text) is that it supports twig, which enables me to get exactly the title I want despite complex circumstances. However, because of the current character limitation associated with this field being of type textfield, I am unable to code the complex twig use cases that I need.

Can we have this field changed to type textarea so that those users who know and love twig, and have rigid/complex use cases, can use this field to it's fullest potential?

In the mean time, if someone has suggestions for how I could achieve this with a template override, I am all ears. Not too eager on developing a custom module for the sole purpose of calling one of the title hooks, but would entertain suggestions there as well.

This issue isn't really a bug, or feature request. Its a simple change request, but not a new feature. If you all decide it should be marked with a different category, by all means change it.
