Progress bar doesn't stay in a single line on iPhone

### Checklist

### Configuration

Blink version: 14.0.0
iOS version: 15.0.2
iPhone model: iPhone X

### Describe the bug

SSH into a Mac and upgrade Homebrew (`brew upgrade -g`). During the download process, the progress bar would use a new line each time the progress updates, instead of staying in the same line.

In my tests, this bug only appears on the iPhone's portrait mode, but not the iPhone's landscape mode or the iPad.

The download progress bar should stay in the same line, from 0% to 100%.


Reproduce `brew upgrade -g` over SSH on an iPhone in portrait mode, then compare the progress output with landscape mode and iPad behavior. Trace the terminal progress rendering path and consider the issue done when updates remain on one line from 0% to 100% in portrait mode without regressing the other layouts.
