stencil whitespace/newline handling around section tags

[StormLord07]

While experimenting with glz::stencil, I noticed that whitespace and newlines around section tags ({{#...}} / {{/...}}) don’t always behave as I would expect.
In some cases an extra leading newline appears, and in others items are concatenated on the same line.

This might be correct and intentional, but it feels a bit strange. I’d like to confirm what the intended behavior is. Each case has comment on expected result below

godbolt

If this is expected how could I achive something like in expected result of examples? Or the only way is to manually format each item?

Update:

I looked through code, whilst trying to understand if that's intended

assuming test case like that

std::string_view layout =
         R"({{#items}}{{text}} {{#completed}}✓ {{/completed}}{{^completed}}○ {{/completed}} {{/items}})";

      TodoList list{
         "Mixed Tasks", {{"Task 1", false, "high", "home", 1, 0}, {"Task 2", true, "low", "home", 1, 0}}, true, 2};

      auto result = glz::stencil(layout, list);
      expect(result == "Task 1 ○ Task 2 ✓ ");

That passes. the space is preserved inside of {{completed}} but inside of the {{items}} it is not, however it is preserved when it starts with it
Other examples:

R"({{#items}}{{text}} {{#completed}}✓{{/completed}}{{^completed}}○{{/completed}} {{/items}})"; // "Task 1 ○Task 2 ✓"
R"({{#items}}{{text}} {{#completed}}✓ {{/completed}}{{^completed}}○ {{/completed}} {{/items}})"; // "Task 1 ○ Task 2 ✓ "
// BUT it is preserved at start
R"({{#items}} {{text}} {{#completed}}✓{{/completed}}{{^completed}}○{{/completed}} {{/items}})"; // " Task 1 ○  Task 2 ✓ "

I'll just leave it here for people to be wary of. And I also made a PR to maybe fix it.I looked through code, whilst trying to understand if that's intended
