Hover-over pop-up for long entries fails when the entry is larger than what can appear within the terminal size

**Before Proceeding, please acknowledge**: - [x] I have consulted the [Troubleshooting guide](https://harlequin.sh/docs/troubleshooting/index). - [x] I have searched Issues and Discussions in this repo. - [x] Feature requests should be initiated as Discussions. This is a bug report. **Describe the bug** I have a Postgres DB with a JSONB column and the entries are quite large in length. When I hover over the column value to initiate the hover-over "popup" tooltip which displays all of the data, the popup appears for a fraction of a second before disappearing. After a second or so it tries to open again, and immediately closes once again. This behavior repeats indefinitely as the mouse is hovering over an entry to initiate the popup. **To Reproduce** Open a DB with that has columns that contain lengthy values. Hover mouse over the entry to initiate popup. **Expected behavior** Popup appears and shows all of the data, or at least truncates the data within the maximum viewable area. **Actual behavior** Popup appears for a split second, then immediately closes. Reappears shortly later and immediately closes. This behavior repeats. **Contributing** Are you interested in contributing a fix? - [ ] Yes - [ ] Maybe - [x] No What is the output of `harlequin --version`? ``` harlequin, version 2.4.1 Installed Adapters: - postgres, version 1.3.0 - duckdb, version 2.4.1 - sqlite, version 2.4.1 ``` What database adapter are you using with Harlequin?
