HTML-code breaks displaying of multi-line column with RichText in PowerApp Canvas App

I have a canvas app that works on the basis of a SharePoint list. I work in an environment where a researcher makes a work order, this is then sent to the responsible that has to approve it, then the planner plans it and following that, it is executed. This chain of events is all managed with a SharePoint list that has a status that can be changed. Different people have different permissions to edit items. To manage this, we display the list through a CanvasApp where logic is built to ensure that people with a certain role can only select/edit/see certain items. 

However, a big part of the canvas app is the description of the work order. In the SP-list this is a multi-line field where RichText is enabled. When the work order description is long, and especially when rich text formatting is used (for example colored text), part of the content is displayed incorrectly. The text gets cut off, part of the HTML formatting code appears in the description itself, and the full content is no longer shown. 

This is an example of a list item:

Which is displayed in the Canvas App like this:

What I observed is the following:

• In the normal SharePoint list view, the description is displayed correctly.
• But when I click/open the item in singe item view itself in SharePoint, the editor/form also .
• This issue only occurs for items that are created from the Canvas App.
• If I create a similar item directly in SharePoint and enter a comparable formatted description there, the problem does not occur.

So it seems the issue is related to how the Canvas App saves the rich text content to SharePoint. It must have to do something with the way PowerAutomate parses that HTML code into SP.
