possible problem parsing INFO description field

Reproduziere das Problem mit dem im Bericht gezeigten INFO-Datensatz und untersuche den geparsten Wert unter vh@header@listData$INFO$Description[93]. Verfolge nach, wie das Description-Feld des Headers geparst wird, und konzentriere dich dabei auf das Gleichheitszeichen innerhalb des in Anführungszeichen gesetzten Texts. Erledigt ist die Aufgabe, wenn die vollständige Description einschließlich des Versionstexts nach dem Gleichheitszeichen erhalten bleibt.

An INFO record like

##INFO=<ID=VRS_Allele_IDs,Number=R,Type=String,Description="The computed identifiers for the GA4GH VRS Alleles corresponding to the GT indexes of the REF and ALT alleles [VRS version=2.0.1;VRS-Python version=2.1.1]">

is processed to

> vh@header@listData$INFO$Description[93]
[1] "The computed identifiers for the GA4GH VRS Alleles corresponding to the GT indexes of the REF and ALT alleles [VRS version"

Something about the equals sign causes truncation of string?
