### Bug report

```markdown
I have one or more legend labels that need to span multiple lines, which I achieve by placing a newline character into the label string (`\n`). In either vertical or horizontal orientation of the labels, this causes excess space to be added to label elements that occur below the multiline label.
```

### Steps to reproduce

```markdown
Go to https://commerce.nearform.com/open-source/victory/docs/victory-legend#data
Paste the following into the text box:

The following is an example for horizontal orientation:

```

### Expected behavior

```markdown
Space between legend elements would remain consistent, either respecting `rowGutter` so the user of Victory can account for this, or automatically for every row.
```

### Actual behavior

```markdown
Excess space is added to only the next row of legend items.
```

### Environment

- Device: Desktop
- OS: macOS Sonoma 14.2.1
