Describe the bug
An if branch containing only a comment causes a parsing error.

To Reproduce

if len(children) > 0 {
	<li>
	@subNav(children)
	</li>
} else if ! navigator.Data.IsSection {
	// don't render a link for empty sections
} else {
	<li>
		@docLoadingLink(vm, navigator, isActive, breadcrumb)
	</li>
}

This parses in v0.3.865, but in v0.3.887 this yields parsing error: string expression: missing close brace. The problem may have started earlier.

Expected behavior
It should parse correctly.

(✓) go [ location=/Users/steve.ruble/go/pkg/mod/golang.org/toolchain@v0.0.1-go1.24.3.darwin-arm64/bin/go version=go version go1.24.3 darwin/arm64 ]

(✓) templ [ location=/Users/steve.ruble/go/bin/templ version=v0.3.894 ]

Additional context
This is not a big problem and can be worked around by using a blank switch { instead (which is arguably more idiomatic and clearer). But it's surprising to have a weird parsing error when dependabot upgrades templ so I thought it was worth reporting.
