possible problem parsing INFO description field

Tái hiện vấn đề với bản ghi INFO được hiển thị trong báo cáo và kiểm tra giá trị đã được phân tích tại vh@header@listData$INFO$Description[93]. Theo dõi cách trường Description của header được phân tích, tập trung vào dấu bằng bên trong phần văn bản được đặt trong dấu ngoặc kép. Hoàn thành khi toàn bộ Description, bao gồm cả phần văn bản phiên bản sau dấu bằng, được giữ nguyên.

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?
