Switching focus erases text field

[jtanium]

Please answer the questions below, it helps us to track the issue.

1. Database version (Ex: PostgreSQL 10.0):
   Not applicable (but in my case PostgreSQL 13.4)

2. TablePlus version (the number on the welcome or about screen, Ex: build 81):
   v0.1 (214)

3. Linux distro (Ex: Ubuntu 18.04):
   Ubuntu 22.04

4. The steps to reproduce this issue:
   Double click on a table, then double click on a value in a row (empty or otherwise) and type in a value. Without pressing enter, switch to another app (e.g. alt-tab) and the value will be erased/reset.

It's a small thing, but still kind of frustrating when you are trying to quickly copy and paste a few values.

The macOS version does not behave in this way, if you switch to another app and back, the value will remain.
