`html_text` getting entities wrong

[GabrielRF]

Steps to reproduce

1: Create a bot with:

@bot.message_handler(func=lambda message: True)
def echo_message(message):
    bot.reply_to(
        message,
        f'{message.html_text}',
        parse_mode='HTML'
    )

2: Send to the bot:

<blockquote>
<b>bold</b> <i>italic</i> <b><i>bold and italic</b></i>
</blockquote>

3: It will reply:

<b><i><blockquote>
bold italic bold and italic
</blockquote></b></i>

Original message:

"text": "bold italic bold and italic",
  "entities": [
   {
    "offset": 0,
    "length": 27,
    "type": "blockquote"
   },
   {
    "offset": 0,
    "length": 4,
    "type": "bold"
   },
   {
    "offset": 5,
    "length": 6,
    "type": "italic"
   },
   {
    "offset": 12,
    "length": 15,
    "type": "bold"
   },
   {
    "offset": 12,
    "length": 15,
    "type": "italic"
   }
  ]
