Editor Log flickering on continuous text

[KoBeWi]

Godot version

v4.1.beta.custom_build [ea6a141]

System information

Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 (NVIDIA; 30.0.15.1403) - Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz (8 Threads)

Issue description

I noticed editor log misbehaving when a text is being printed. It seems to be mostly noticeable (or exclusive to?) when collapsing of duplicate messages is enabled.

It looks like the log rebuilds from scratch with every message. If it had already some content, the text might be printed faster than it appears, causing it to be unreadable:

Steps to reproduce

func _process(delta: float) -> void:
	print("spam")

Minimal reproduction project
