Interestingly, the title with a second line starting on SAMD9 was not affected, while the abstract was truncated with this term. But when changing this name in the title to AU - MD9 even the title gets truncated without warning, here is a minimal example where the title is truncated as well:

PMID- 000000000000
OWN - NLM
STAT- In-Process
LR  - 20200715
TI  - Outcomes of Hematopoietic Cell Transplantation in Patients with Germline
      AU - MD9/SAMD9L Mutations.
PG  - 2186-2196
LID - S1083-8791(19)30439-2 [pii]
LID - 10.1016/j.bbmt.2019.07.007 [doi]
AB  - Germline mutations in SAMD9 and SAMD9L genes cause MIRAGE... A patient with
      SAMD9L-associated MDS died of diffuse alveolar hemorrhage. 
FAU - Ahmed, Ibrahim A
AU  - Ahmed IA

The - in the regex

translators/MEDLINEnbib.js

Line 181 in cc92035

else if (line.search(/^[A-Z0-9]+\s*-/) != -1) {

and the missing consideration of leading spaces for each line due to stripping them all here

translators/MEDLINEnbib.js

Line 161 in cc92035

line = line.replace(/^\s+/, "");

explain why SAMD9L-associated triggered the processing of the tag up to that point in the abstract, but not in the title.

Another minimal exmample, this time only the title gets truncated:

PMID- 000000000000
OWN - NLM
STAT- In-Process
LR  - 20200715
TI  - Mickey Mouse had an 
      O-some day!
AB  - Mickey Mouse had a quiet day until something happened and
      SAMD9L was caught in the end. 
FAU - Mouse, Mickey
AU  - Mouse M
