Why rendered Markdown cells in my Jupyter notebook in Visual Studio Code appears overlaid?

In my VS Code, when I open a Jupyter notebook the rendered text in Markdown cells does not appear right.

When I double click the cell, and I am able to enter the edit mode. In this case, the text appears as normal. But when I execute the cell, the rendered text again gets overlaid. There are no such problems with the code cell.
What might be the exact issue?

I tried opening in PyCharm, there the notebook renders just fine. I have tried to create my own notebook as well, there too I am facing the same markdown cell rendering issue.
