There is no label "recently used" next to the used context after executing "Use" action

[v-xinda]

OS: All Build Version: 20231012.1 Regression: Not a regression

Repro Steps:

1. Expand "Contexts" view.
2. Right click the unused context (like "default") -> Click "Use".
3. F1 -> Docker Contexts: Use.
4. Check whether there is a label "recently used" next to the used context.

Expect: There is a a label "recently used" next to the used context.

Actual: There is no label "recently used" next to the used context.

More Info:

1. This issue doesn't reproduce after executing "Docker Contexts: Use" twice for the same context from command palette.
2. On Windows, if you want to change the context "desktop-linux" to "desktop-windows", the label still doesn't appear after executing "Docker Contexts: Use" twice.

@bwateratmsft We haven't touched this side of the extension, I'm thinking this could be related to the Docker Desktop update?

[bwateratmsft]

No, this "recently used" behavior is provided by the @microsoft/vscode-azext-utils package. Could be an update there busted it. We should investigate if the problem is widespread or just affecting contexts; if it's only contexts then it can definitely wait.

Okay sounds good.

@bwateratmsft It still works on Docker Images: Run, so i think we should be okay. Is there any other command we should see if this works on?

I think I figured out what's happening. The underlying objects are changing--i.e. from "selected = false" to "selected = true"--so the hash code changes and recently used doesn't work. If you choose the same context several times in a row (even though to do so is redundant), it starts working again because the object doesn't change when it's already selected:

I think we can won't-fix since it using the same context over and over again isn't something users need to do.
