In WordPress 5.8 we added the ability to only load styles for blocks when these blocks are rendered. However, these optimizations left out block-styles that get added using the register_block_style() function/API.

This avoids a fatal error on PHP 8 caused by passing a zero value to `fread()` as the `$length` argument, which must be greater than zero.
This commit also amends the previous solution for similar issues elsewhere in the file to ensure consistent type for string values, instead of changing the type from `string` to `bool` when trying to read from an empty file.

The `serializeAttributes()` function in JavaScript uses `JSON.stringify`, which does not encode slashes and unicode characters by default. This resulted in the PHP serialization through `json_encode()` producing different results.
This also switches from `json_encode()` to `wp_json_encode()` to prevent failures when any non UTF-8 characters are included.

Previously, the original "404" template key was lost when "Default template" is merged into the available templates array, as the `array_merge()` function renumbers numeric keys. Later, when we merge templates on the client side, this caused duplicate "404" templates to appear in the dropdown.
By replacing the `array_merge()` call with `array_replace()`, we make sure to keep the original numeric keys.

This avoids a "Table `wp_options` doesn't exist" database error when trying to create a nonce for password reset button.
When installing and using database-saved salts, `wp_create_nonce()` causes database errors as `wp_salt()` attempts to insert into the not-yet-created options table. Since authentication is not available during installation, we can safely skip creating a nonce.

* Twenty Ten: Version 3.5 (fatal error & 404)
* Twenty Eleven: Version 3.9 (404)
* Twenty Twelve: Version 3.5 (404)

- A single `-webkit-` prefix is removed for `min-width`, which was required for Safari <= 10.1 (0.06% total global usage). WordPress only supports the last two versions.
- 2 instances where the `-o-` prefix are added for `tab-size`. This appears to be for Opera Mobile, which has creeped back over the 1% global usage.

More testing has revealed that the `image_editor_output_format` filter has some interesting edge cases that developers should be aware of when electing to use this filter (see #53667 and #53668).
Because this is a new filter that was intended to be used for experimenting with different ways to handle generating image sizes and has not yet been adopted in the wild, expanding the inline documentation is an acceptable temporary solution while these edge cases are explored further and addressed.

This fixes a bug where widgets are unintentionally moved to the `wp_inactive_widgets` sidebar when batch updates occur through the REST API.
When batch requests are processed, only `$_wp_sidebars_widgets` is updated by previous calls to `WP_REST_Widgets_Controller::create_item()`. `$sidebars_widgets` is not aware of the new widget’s intended location, and `retrieve_widgets()` mistakenly flags the widget as inactive.
Calling `wp_get_sidebars_widgets()` before `retrieve_widgets()` ensures both global variables match and is intended as a temporary fix until the root cause of the problem can be fixed.
