Custom priceFormatter causes line to disappear when no data variance

[Fyko]

Lightweight Charts™ Version: 4.1.7

Issue
When using a custom priceFormatter to create a text display for very large numbers, when all the current data for the chart is the same, no area/line is shown.

Sample code:

• Implementation of custom priceFormatter
• Chart definition

Live example

I tried to reproduce this with a simple example, and it seems that the issue only occurs with numbers around 1 quadrillion in size.

I would suggest reducing the size of the number before providing it to the library (via setData).

I'm glad to see you've been able to reproduce! Unfortunately, I can't reduce the size of my data
