Tested versions

• Reproducible in v4.3.beta.custom_build [6b281c0]
• I have not tested this issue in prior versions, but I don't remember this behavior in Beta 1 or any previous version of Godot
• Custom build is for the double-precision flag

System information

Godot v4.3.beta (6b281c0) - Windows 10.0.22631 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 3050 Ti Laptop GPU (NVIDIA; 31.0.15.3598) - AMD Ryzen 7 5800H with Radeon Graphics (16 Threads)

Issue description

The built-in GDScript editor's cursor behaves unexpectedly, inconsistently, and incorrectly, compared to previous versions and editor norms.

Clicking Ctrl-Left and Ctrl-Right makes the cursor skip several tokens at once. Not all code lines suffer from this, and this only happens in "code" lines and not inside comments as far as I can tell.

Steps to reproduce

• Create or open an existing script
• Navigate to lines that contain code
• Click Ctrl-arrow keys and watch the cursor erratically; Sometimes skipping 1 token and at other times skipping several tokens at once.

You can use this as an example line:

expect(red.has_method("deactivate")).to.be.truthy("Some generic description of the test")
	red.deactivate()

Positioning the cursor at the start of the expect token then Ctrl-Right Arrow clicking shifts the cursor to the end of the word "Some skipping all the tokens and spaces in between.
