title: R Shiny colResize restore column widths
body: <p>Following up on <a href="https://stackoverflow.com/questions/72256689/r-shiny-communicate-column-sizes-between-r-and-javascript-with-colresize">this</a> post, I seem to have forgotten to include an important thing in my question. I would also like to restore the column width that was communicated to R.
  How can I expand the code from the answer to my previous question in an idiomatic way to include such a functionality?</p>
