live_title contains newlines

[lifeiscontent]

Environment

• Elixir version (elixir -v):
  Erlang/OTP 27 [erts-15.1.2] [source] [64-bit] [smp:10:10] [ds:10:10:10] [async-threads:1] [jit]

Elixir 1.17.3 (compiled with Erlang/OTP 25)

• Phoenix version (mix deps): 1.7.18
• Phoenix LiveView version (mix deps): 1.0.1
• Operating system: MacOS
• Browsers you attempted to reproduce this bug on (the more the merrier): N/A
• Does the problem persist after removing "assets/node_modules" and trying again? Yes/no: N/A

Actual behavior

using mix format

    <.live_title default="Page" suffix=" · Phoenix">{assigns[:page_title]}</.live_title>

is always formatted to:

    <.live_title default="Page" suffix=" · Phoenix">
      {assigns[:page_title]}
    </.live_title>

which results in this output:

<title data-default="Page" data-suffix=" · Phoenix">
      Privacy Policy
     · Phoenix</title>

Expected behavior

<title data-default="Page" data-suffix=" · Phoenix">Privacy Policy · Phoenix</title>

Is this a real problem? The title still shows correctly, as newlines are ignored. If you don't want the formatter to change the live_title, you can add phx-no-format:

<.live_title default="Page" suffix=" · Phoenix" phx-no-format>{assigns[:page_title]}</.live_title>
