Attachment: firefox-caret-extra-pixel-video.gif

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/112.0

Steps to reproduce:

Click on any text input in Firefox (e.g. <textarea>, the URL bar, dev tools' "Search
HTML" input...), and look at the caret.

Actual results:

The blinking editing caret has a white pixel on the right side of the caret, one pixel below the top-most pixel. It can be seen more clearly if you zoom in with Ctrl and +.

Expected results:

The caret should be a simple line without any extra pixels.

Closing, as I learned that this is intended behaviour. I had both LTR and RTL keyboard layouts installed, and had just enabled bidi.browser.ui in the configuration, which was what caused the bidirection indicator pixel to appear.
