follow up to #5812, which was closed prematurely, without fixing the issue.

On macs with 1.7.5, the labels are still misaligned:

We are not able to reproduce this anymore. What is the result if you do this on https://mermaid.live/ on Safari?

[samuelpmish]

using the default mermaid.live example

flowchart TD
    A[Christmas] -->|Get money| B(Go shopping)
    B --> C{Let me think}
    C -->|One| D[Laptop]
    C -->|Two| E[iPhone]
    C -->|Three| F[fa:fa-car Car]

I get the following

mermaid.live:

typora version 1.7.5 (7015):

I get the same results (with vertically offset text labels) on two different macs, but things look correct on my ubuntu 22.04 machine.
