Emoji reactions appear pixelated
- [x] I have searched open and closed issues for duplicates
Bug Description
Emoji reactions on screen with low PPI look pixelated which makes them hard to distinguish from one another. By looking at https://data.firefox.com/dashboard/hardware you could conclude that large number of web users are still using low resolution screens. I think it would make sense to increase the size of reaction emojis and make it equal to the size of emojis from message bubbles to make reactions more readable.
Screenshots
Some reaction emojis lose a lot of details even though they're only 5 pixels smaller than emojis from message bubble.

Platform Info
Signal Version: Signal Desktop 1.34.1
Operating System: Kubuntu 20.04 21.5" (1920x1080) screen (~102 PPI)
What you describe seems very subtle, but if I get my head very close to my screen, I believe I can see what you are describing, in particular in test 2 (the eyebrow at the right) and test 4 (the eyes) and a little bit in test 1 (the round shape).
If that's all you mean, I can reproduce with Signal 7.43.0 on Microsoft Windows 11. It's worth noting that clicking on a reaction opens a dialog with details. Unfortunately, the emoji are just as small in that dialog. I would recommend to first enlarge these.
