Custom Vector tile data display crashes under load

[Bonkles]

Description

It appears that loading custom vector tile data can, in certain circumstances, cause RapiD v2 to give up and fall over. Severe slowdowns, not showing all the data in each layer, etc. are just a couple of the issues we're seeing in internal testing.

Version

2.0.0-beta.0

What browser are you seeing the problem on? What version are you running?

Chrome 109.0.5414.119

Steps to reproduce

Load custom vector tile data using the Map Data (F) menu, click 'edit custom map data' button, paste the vector tile data URL, observe RapiD slow to a crawl / not display everything.

The browser URL at the time you encountered the bug

http://127.0.0.1:8080/#background=Maxar-Premium&datasets=fbRoads,msBuildings&disable_features=boundaries&map=15.00/48.8742/2.3415 but with an internal vector tile dataset.

Fixed in e8e79c5.

There were a few issues here:

1. Container ids for custom data containers had 'undefined' elements
2. The projection being fed into the custom data viewer didn't have a projection boundary- so only tiles in the upper left of the screen were being loaded on startup.
3. Ensure that we re-render any custom data features that get updated (say, those getting merged into other features with the same feature class).
