There seems to be a limit to the length when writing to html. and will be automatically truncated.

I added some code to the example for testing：

1. Read html and print the length into the htmlString variable

   <button
   type="button"
   class="btn variant-filled block btn-sm"
   on:click={() => {
       clipboard.readHtml().then((t) => {
           html = t;
           htmlString = t;
           console.info(`%cread HTML Length: ${htmlString.length}`, 'color: red');
           console.log(htmlString);
       });
   }}
   >
   Read HTML
   </button>

2. Write htmlString unchanged to clipboard and read clipboard html length again

   
   <button
   type="button"
   class="btn variant-filled block btn-sm"
   on:click={async () => {
       await clipboard.writeHtml(htmlString);
       clipboard.readHtml().then((t) => {
           html = t;
           console.info(`%cwrite HTML Length: ${t.length}`, 'color: red');
           console.log(t);
       });
   }}
   >
   Write HTML
   </button>

result：

I did this experiment on Mac and Windows. Mac had no problem writing a large html, but windows couldn't handle large html.

use clipboard_rs::{ClipboardContext, Clipboard};

fn main() {
    let ctx = ClipboardContext::new().unwrap();
    let html = std::fs::read_to_string("./text.html").unwrap();
    println!("Length (original): {}", html.len());
    ctx.set_html(html).unwrap();
    let html = ctx.get_html().unwrap();
    println!("Length: {}", html.len());
}

stdout

Length (original): 132205
Length: 205

Reading html on Windows works. Reading and writing on Ubuntu work.
