fontSize themeVariable setting is ignored

[t-ir]

Description

The erDiagram below appears with writing that is too small to read regardless of the value supplied for fontSize. There's no obvious effect on flowDiagrams either. I am using a 4k monitor.

Steps to reproduce

%%{
init:
{
'theme': 'base',
'themeVariables' :
{
'fontSize' : 100
}
}
}%%
