When using bookdown (single document), if I set both section_numbering = 'yes' and fig_caption = 'yes', the figures are numbered X.2 (where X is the section number). If section_number = 'no', the figures are numbered sequentially (Fig 1, 2 ...), but sections numbers are lost.

Is there a way to get figures numbered sequentially without losing the section numbers? In the example below, I would like to have both the sections figures numbered as 1 and 2.
I had posted this question on stackoverflow and I was suggested to fill an issue.

Thank you.

Reference example: \@ref(fig:plotcars):
```{r plotcars, fig.cap = "A car plot"}
plot(cars)
```
# header 2
Reference example: \@ref(fig:plotcars2):
```{r plotcars2, fig.cap = "A car plot"}
plot(cars)
```
