Popup lazy by default

[BastienGauthier]

Hello map makers !

As for generic behaviour in python modules, should the Popup be lazy by default, to save some performances ?

I found the lazy behaviour only implemented here, so I guess the change is only to switch this default to True:

Hi Bastien, interesting suggestion! I could argue for both sides, whether to keep it False or set it True. What you say makes sense. But maybe for some users it’s preferred to not have to wait when they open a Popup.

When in doubt regarding a choice for Folium, I tend to stick with how things are, rather than allow a breaking change. Changing the default is a breaking change, so that’s why I’m hesitant.

So my question to you is: is it more beneficial to change the default setting than the risk it costs of upsetting some users workflow?

I guess it is only a matter of green computing good practice in this case. Anyway, I agree it could be a notable performance change for some people, so it would at least need a minor version of "FutureWarning" I guess.

Not sure if this could break anything though, I don't have any use case in mind. The only advantage of greedy behaviour would be if someone makes a graphs embeded in a few popup, and wants them instantly when clicked. But popups are often text, so the unitary loading time is negligible.
