Missing vertical borders with Windows Terminal

### Describe the bug
For some reason after I've installed Dracula theme in my WSL Windows Terminal Tmux session it broke my vertical bars while splitting a given window. It is interesting that the horizontal border works (as you can see in my screenshot)

Before installing Dracula, it was working as expected.

### To Reproduce
Steps to reproduce the behavior:
1. Open a Windows session
2. Install WSL with any distro
3. Setup tmux
4. Split and check that it is working
5. Install TPM and Dracula theme
6. Split and see the bug

### Expected behavior
The vertical border should exist, like the horizontal one.

### System
- OS: Windows 11
- Tmux Version: 3.2a
