Image caption formatting lost when switching from Source to Visual mode

[lvclark]

Bug description

When I put image caption text in italics, add a link to the image, switch to Source as the editor, then switch back to Visual as the editor, the italics formatting is lost. The example document below reproduces this behavior. (I also lose caption formatting on one of my pages when rendering the document, but am unable to reproduce that behavior with the example below.)

Steps to reproduce

title: "Bug Example"
author: "Lindsay Clark"
---

```{r}
png("example_image.png")
plot(1:10, 1:10)
dev.off()

### Expected behavior

When I switch back and forth between editors, I expect the formatting to say the same.

### Actual behavior

The asterisks that indicate italics formatting get stripped out of the document. I tried HTML tags, and these are also lost.
