The styles that are denoted with an asterisk (*), when defined,
completely override the default spans. The others, when defined, add
spans before the default spans (if any) so that when reversed, take
precedence. Example:
```
<ru.noties.markwon.view.MarkwonViewCompat
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:mv_H2Style="?android:textAppearanceLarge"
app:mv_markdown="## Opening hours" />
```
In the above case, as ?android:textAppearanceLarge most likely is
resolved into an actual style, the spans that are added by the Markwon-
library (including heading line break) will no be added.
```
<ru.noties.markwon.view.MarkwonViewCompat
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:mv_CodeSpanStyle="?textAppearanceSmall"
app:mv_markdown="`private int count = 5`" />
```
Conversely, defining a style for mv_CodeSpanStyle will still result in
that background is added to the code text and it will by styled
according to the resolved style of `android:textAppearanceSmall`.
