Research direction

Start from the toggleMark(range:color:resetColor:) entry point and reproduce the issue on iOS 18 with Chinese input, entering characters continuously. Inspect how the marked range and generated HTML change after composition pauses; done means the color remains applied and getHtml produces one mark element covering the complete input, such as “我是”.

iOS 18 and Chinese input，

I used toggleMark but found a bug. In Chinese, the color would break when input continuously.

It is certain to occur.

To Reproduce
Steps to reproduce the behavior:

  1. Go to 'empty page'
  2. Click on 'richTextView.toggleMark(range: richTextView.selectedRange, color:.green, resetColor: false)'
  3. iOS18 , Chinese input。我(停顿)是
  4. 是 has become black

Image

<p>123<mark style="background-color:rgba(0, 0, 0, 0);color:#ffff9500" class="has-inline-color">我</mark>是</p>

The display is orange, but what html gets is the absence of the mark tag

Expected behavior
getHtml is true is:

<p>123<mark style="background-color:rgba(0, 0, 0, 0);color:#ffff9500" class="has-inline-color">我是</mark></p>
