When plot pane is closed and reopened plot does not appear until positron is resized

[testlabauto]

Positron Version: 2024.07.0-81

Steps to reproduce the issue:

1. Create a plot

import plotly.express as px
fig = px.bar(x=["a", "b", "c"], y=[1, 3, 2])
fig

2. Close the plots pane
3. Reopen the plots pane
4. Note that plot is not visible
5. Resize positron
6. Note that plot is visible again

What did you expect to happen?

When plot pane is reopened plot appears without needing to resize positron.

Were there any error messages in the Output panel or Developer Tools console?

No

I've also seen somewhat similar behavior with the data explorer cc @petetronic - maybe the same issue?

This is like the problem we had with Help in #2656.

Strange, this was a case I definitely manually tested. Also in Positron Version: 2024.07.0 (Universal) build 85 it works as expected for me:

On Positron 2024.07.0 (Universal) build 85, I see the same problem that @testlabauto observes:

FWIW I confirmed that

• static plots are fine (this is HTML interactive plots only, but both R and Python)
• Help still works as expected
