Description

#### ALL software version info
(this library, plus any other relevant software, e.g. bokeh, python, notebook, OS, browser, etc)
hvplot 0.9.0
bokeh 3.3.2
panel 1.3.4
holoviews 1.18.1
jupyterlab 4.0.9
#### Description of expected behavior and the observed behavior
This happened after update of bokeh from 3.3.1. There are two issues:
1. When the code below is run in code cell, it does not display. The same code works when typed in the associated console. However, when I close and reopen the notebook, the image is shown in the code cell.
2. Another problem is that the select widget does not work (when displayed in console): the items can be selected, but the image does not change.
I tried both firefox and chromium browsers. The javascript console log output is shown below.
#### Complete, minimal, self-contained example code that reproduces the issue
```
# code goes here between backticks
import panel as pn
import hvplot.pandas # noqa
from bokeh.sampledata.iris import flowers
flowers.hvplot.bivariate(x='sepal_width', y='sepal_length', width=600,
groupby='species')
```
#### Stack traceback and/or browser JavaScript console output
```
