Branch Coverage Calculation changed in Jest v30?

[SchroederSteffen]

We noticed in several typescript-based projects that the branch coverage is calculated differently somehow in Jest v30 compared to v29.
I couldn't pin-point and create a minimal reproduction yet. My reproduction works the same in v29 for some reason.

In most cases it seems to be around (not) going into a not-existing else branch of an if.
Seems like an if without else was considered only a single branch before?

It was also mentioned here: thymikee/jest-preset-angular#3152 (comment)

I welcome the change (assuming that I got it correctly), but I would like to understand through which change/PR it came in.
Is this known?
