ligatures starting with a pipe in the terminal only render correctly if selected

[LucasOe]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.97.0
• OS Version: Windows 10 (22H2)

Steps to Reproduce:

1. Open the integrated terminal. I'm using pwsh v7.4.6
2. Enable terminal.integrated.fontLigatures.enabled in the settings
3. Use a font that supports ligatures. I'm using the Fira Code Nerd Font
4. Type |== and |=== and |--- and |-> in the terminal
5. The ligatures only render correctly if the text is selected

I haven't tested this issue with different fonts and different shells.

Same setup (pwsh 7.5.0). With Cascadia font it works fine.

Don't forget

Ligatures are now temporarily disabled while the cursor or the selection is within the ligature.

Trying the same setup using Cascadia Code results in the same result for me. As you can see, the => renders correctly in the screenshots below. I also updated pwsh to 7.5.0 and the problem remains. The same ligatures render correctly in the Windows Terminal.

Ligatures are now temporarily disabled while the cursor or the selection is within the ligature.

This isn't what's causing the problem here. Other ligatures render correctly with the same setup and cursor/selection placement, as seen in the screenshots attached. From my testing only ligatures starting with a pipe are affected, I haven't tested all of them, however.

The same text in a blank editor for reference. Both use the Fira Code Nerd Font in this example.

Sorry, I misunderstood the issue and I tried the ligature without starting a pipe.
Indeed I reproduced the issue, even if only |=== works fine, the rest of your examples are not a ligature here.

No idea, I would say it is related to the font.

Pipe character is like "arrow support" in Cascadia: https://github.com/microsoft/cascadia-code?tab=readme-ov-file#font-features
