[Bug]: Log scaled barplots in PDF result in infinite rectangles

Nobody has claimed this yet.

### Bug summary

When saving log scaled barplots as PDFs, the bars get saved as rectangles with infinite size.

### Code for reproduction

```Python
import matplotlib.pyplot as plt
import numpy as np

categories = ['A', 'B', 'C', 'D', 'E']
values = [800, 1200, 2000, 3000, 5000]

plt.bar(categories, values)
plt.yscale('log')
plt.savefig('Log_scale_barplot.pdf')
```

### Actual outcome

Rectangles with infinite size

### Expected outcome

Rectangles size capped at axis

### Operating system

Linux, OS/X

### Matplotlib Version

3.8.4

### Matplotlib Backend

### Python version

### Installation

None

Start by running the provided Python reproduction with Matplotlib's PDF save path and inspect how log-scaled bar rectangles are handled during PDF rendering. Compare the generated rectangles with the expected axis bounds, then add a regression test showing that their size is capped at the axis instead of becoming infinite.
