getMessageSegmentInputs not working with "<p style="text-align: center;">Hello</p>"

We are using the lightning-input-rich-text(LWC) and when user using text alignment center|right that time `

Hello

` HTML is generating.

Post we are passing `

Hello

` HTML as **param**(inputText) to **getMessageSegmentInputs** method, but this piece of code **String textSegment = inputText.substring(strPos, globalMatcher.start());** returning invalid HTML, hence system throwing error.

Output of **textSegment** post executing code:
`

Hello`

Error:
Error while parsing Rich Text Content: The markup in the document following the root element must be well-formed.

Could you please help us to resolve this issue.
