From ea71ff8ef7cec79cfbe728c4442fa584efb15ebb Mon Sep 17 00:00:00 2001 From: Dylan Hunn Date: Thu, 14 Dec 2023 10:56:35 -0800 Subject: [PATCH] refactor(compiler): Fix self-closing element source spans in template pipeline (#53574) When an element is self-closing, it will cause an `element` instruction to be emitted (instead of `elementStart`/`elementEnd`). In that case, we should use map whole source span for the instruction, not just the starting span.
