TextEdit doesn't wrap the first word of a line

Manjaro Linux, kernel 6.1.1-1-MANJARO, AMD Ryzen 5 3600, AMD RX 580

Issue description

The wrap_mode property of the TextEdit node doesn't seem to really do anything. Setting it to LINE_WRAPPING_BOUNDARY simply means that there won't be an horizontal scrollbar if the text overshoots the boundary, instead of actually forcing the text to the next line so that it stays visible.

Steps to reproduce

Create a TextEdit node and set its wrap_mode property to LINE_WRAPPING_BOUNDARY

Tried this with 3.5.1, doesn't happen and the text wraps correctly:

Tried going as far back as 4.0 alpha 1, bug is still present

In this example, even though there are many characters, they are treated as a single word. LINE_WRAPPING_BOUNDARY may mean line wrapping between words.

Doing proper text wrapping is complicated, and language dependent if it is to be done properly

I'm sure it is, but it did use to work
Godot 4 doesn't actually give more options for wrapping, it simply swaps a Boolean for an enum whose choices are basically yes or no. Therefore, I'd imagine the underlying behaviour shouldn't change between the two releases.

@Rindbee That was a good suggestion
Yes, it does wrap the next word to the next line if the caret has been pushed beyond the border by the previous one. Furthermore, the real bug seems to be that the first word of a line won't be wrapped if it goes beyond the TextEdit's border, unlike in Godot 3.x where it gets correctly split and wrapped (as shown in the screenshot in my first comment).

This behaviour is not clearly stated in the docs, who simply say (for LINE_WRAPPING_BOUNDARY):
"Line wrapping occurs at the control boundary, beyond what would normally be visible."

E.g.

correct wrapping of second word:

second word wrapped correctly once, but then overflows once it becomes the first of the next line (notice the missing caret):
