Aren't stakeholder expected to adopt an agile mindset when working in a Scrum framework?
What is expected of the stakeholders when it comes to being agile? Since collaboration is at the heart of agile, shouldn't the adoption of agile values be present on both sides?
As per my observations, stakeholders who do not have adequate knowledge of Scrum or agile tend to give the teams a hard time, especially the PO(Product Owner). Shouldn't there be more emphasis on the stakeholder's role in Scrum?

Yes, it should. But often isn't.
The problem is that Agile/Scrum is more of a mindset than a way of working. But people all throughout the organization see it as a methodology for developing software. If you are an executive, a business person, or working in some other department within the company and you need IT to build you software, the historical de facto way of getting it is to ask for it. Stakeholders usually have expectations from the development team, they don't really collaborate with them. It's a different mindset. An old mindset.
You said it in the title of your question that stakeholders are expected to adopt an Agile mindset. That means letting go of their old mindset and embracing a new one. This is the corner stone for having a successful Agile implementation across the company. A new mindset. But this comes with a lot of things attached to it, like changing organizational structures, reorganizing communication channels, changing organizational culture, changing roles and responsibilities, being more involved instead of just asking for things, and much more.
These are not easy things to change, they involve a lot of time and effort, and many times no changes get done. People expect Agile to give them agility, to make them nimble to respond quickly and effectively to change. To give an analogy, they expect to move quickly through water like a speed boat. The problem is that most companies are huge oil tankers that take a lot of space and a lot of time to make even the smallest turns.
