These might have been necessary at one point, but I'm confident they're unnecessary now — increment_pending happens (if necessary) inside flatten, which is called inside async and deferred_template_effect, so there's no need to call it inside those functions as well.

Before submitting the PR, please make sure you do the following

  • It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs
  • Prefix your PR title with feat:, fix:, chore:, or docs:.
  • This message body should clearly illustrate what problems it solves.
  • Ideally, include a test that fails without this PR but passes with it.
  • If this PR changes code within packages/svelte/src, add a changeset (npx changeset).

Tests and linting

  • Run the tests with pnpm test and lint the project with pnpm lint

Nice find, should also make #18118 a bit lighter
