Short description

Mouse clicking, hovering and dragging is always active on an InfiniteLine object drawn at a very small absolute angle irrespective of the mouse position within the view box.

Code to reproduce

import pyqtgraph as pg

import PySide6
import pyqtgraph as pg

app = pg.mkQApp()

plt = pg.plot()
xr=[]
for i in range(10):
    xr.append(i*1.0e+06)

sample = plt.plot(xr,range(10))

infline=pg.InfiniteLine(pos=[1.0e+06,2],angle=4.0e-05,movable=True)
plt.addItem(infline)

plt.show()

app.exec()

Expected behavior

Normal mouse clicking, hovering and dragging behavior.

Real behavior

Mouse clicking, hovering and dragging are always active on the InfiniteLine object regardless of whether the mouse pointer is over this object or elsewhere in the view box. This happens both with the PySide6 and default (PyQt5) config.
