can't copy shortened dataframe cell - ellipsis problem

using Jupyter Lab 4.0.2 and latest versions(should be) of kotlin jupyter and kotlin/dataframe
(don't know how to get kotlin jupyter and kotlin/dataframe version, but I just installed them last week

suppose you have a long text in cell, the current implementation shortens it by truncating the original text
this made it very hard to copy the original text using `CMD-C`/`Ctrl-C` after text selection

the copied text is(incorrectly truncated) `homed_search_word_recommend_12042_v22...`

1. is there a better way to grab the full text?
2. I think the cell should be rendered by the browser, instead of truncated by the backend code, here a demo

the copied text in the above example is(correctly the full text) `DeepAnswerModel_10794_v1_r144669_sail_deep_answer_0`

and https://codepen.io/markchitty/pen/RNZbRE

it would be better if the cell is middle truncated instead of end truncated, but the majority of browsers don't support middle truncation, implementing it would require more code
