[MacOS] In bigger font size, cmd+triple_click doesn't select full contents of the output

[msharran]

Issue

In my Macbook pro 14 inch (Apple M1 Pro Chip) with font size of 15 by default, cmd+triple_click selection leaves out the first line. Refer below image.

But when I do cmd+minus till it wraps the contents in a single line, then it works as expected. Refer below image.

Feature used is Shell Integration
