If I'm using a FlexTemplate and feed multiline text into it. It displays the lines like it does a newline between each line break.
I tried the same text content with a normal multi_cell() and it is displayed just fine. But not in the template.
python version: 3.11.1
fpdf2 version: 2.7.9
Here is my code where you can directly see this behavior:
from datetime import datetime
from fpdf import FPDF
from fpdf import FlexTemplate
ra_address = "Dummy Firstname Lastname Streetname. 123 12345 London"
title = "Y o u A r e A m a z i n g"
logo_path = "assets/Logo-test.png"
generic_info = "Tel.: 000 / 000 000 0 - 0\nFax: 000 / 000 000 1\nMail: hello@example.uk"
created = "Created: "+datetime.now().strftime("%d.%m.%Y")
legend = """My Legend: CL = Countless: 1 = yearly / 2 = half / 4 = quarter / 5 = monthly / 6 = single Options: C = Cookie / ED = Endcake / LW = Lower Water / ST = Storm / IZ = IceZip / GL = Global / UG = Unknown Geodez\u00ad

Thank you
As explained here: https://github.com/py-pdf/fpdf2/issues/1237
The y1 to y2 dimension of multiline text in a template expects the size of a single line, not of the whole block.
Hint: A good value for y2 is: y2 = (font-size/2)+y1.
