Description
Environment: Windows, plotly 6.0.0
Minimum Example:
import plotly.express as px
df = px.data.gapminder().query("continent=='Oceania'")
fig = px.line(df, x="year", y="lifeExp", color="country", title="layout.hovermode='closest' (the default)")
fig.update_traces(mode="markers+lines")
fig.show()
Behavior:
When using selection tools in Plotly (e.g. box select, lasso select), it's not possible to hover over data points inside the selection area. The cursor changes to a "move" cursor and only allows repositioning the selection. Outside the selection area, hovering works normally.
Image 1: Inside the box selection, only the move cursor is visible and hovering is not possible
Image 2: Outside the selection area, hovering works correctly and displays data point information
Suggestion:
A potential improvement would be limiting the move cursor functionality to only the edges of the selection area, allowing users to continue hovering over data points inside the selection.

Research direction
Run the supplied Python minimum example with Plotly 6.0.0 on Windows and reproduce the interaction with box and lasso selection. Trace the selection and hover behavior from the example's figure display, then verify that points inside a selection can show hover information while selection movement remains available at the selection boundary.
