Configure number of lines in the preview popup

[ileodo]

Currently, if I click the date of a transaction in fava, a popup will come up showing the preview of the raw transaction text. However I believe the text got truncated, and turns out the transaction was not displayed properly. (my transaction has a lot of lines of meta data)

Is there a way to fix it or make it configurable?

Thanks

The code to obtain the lines for an entry is here: get_entry_slice. A PR with a fix would be welcome :)

I think the implementation is correct. my ledger file had some issue which caused the problem. thanks!
