sentry-tracing: Fields prefixed with tags. are not sent as tags within spans

[DoumanAsh]

Environment

What version are you running? Etc.

0.32.2

Steps to Reproduce

1. Create tracing span:

tracing::span!(
    tracing::level::INFO
    "request",
    tags.http.url = field::Empty,
    tags.protocol = field::Empty,
    tags.request_id = field::Empty,
    user_agent = field::Empty,
    tags.http.method = field::Empty,
    tags.http.status_code = field::Empty,
)

3. For the duration of requests, these fields will be filled with data
4. Unfortunately when I open sentry to see event, it shows no tags and instead all fields are sent as Additional Data

I see in code how it checks for tags presence

sentry-rust/sentry-tracing/src/converters.rs

Lines 155 to 179 in 1df2e4c

	fn tags_from_event(fields: &mut BTreeMap<String, Value>) -> BTreeMap<String, String> {
	let mut tags = BTreeMap::new();
	fields.retain(|key, value| {
	let Some(key) = key.strip_prefix("tags.") else {
	return true;
	};
	let string = match value {
	Value::Bool(b) => b.to_string(),
	Value::Number(n) => n.to_string(),
	Value::String(s) => std::mem::take(s),
	// remove null entries since empty tags are not allowed
	Value::Null => return false,
	// keep entries that cannot be represented as simple string
	Value::Array(_) | Value::Object(_) => return true,
	};
	tags.insert(key.to_owned(), string);
	false
	});
	tags
	}

But it seems not to be applied to transactions?

Expected Result

See tags in sentry

Actual Result

Fields are sent as additional data
