TextAreaInput - implementing/dropping cols param?

Panel 1.6.2a1

Description of expected behavior and the observed behavior

The Panel docs says cols is the number of columns in the text input field, which is quite confusing. The Bokeh docs makes it clearer, cols specifies the width of the text area (in average character width). However, instantiating different TextAreaInput widgets with different cols doesn't seem to make any differences. Looking at the code, not sure if cols got implemented actually. As we allow setting the width of widget with width param. How about dropping the cols entirely?

Complete, minimal, self-contained example code that reproduces the issue

import panel as pn

# looks like we also allow negative/0 cols
pn.widgets.TextAreaInput(cols=-1).servable()
pn.widgets.TextAreaInput(cols=0).servable()

pn.widgets.TextAreaInput(cols=1).servable()
pn.widgets.TextAreaInput(cols=100).servable()
pn.widgets.TextAreaInput(cols=200).servable()
