Cypress began to inject additional markup into the downloaded csv, tsv & txt files (after v. 10.9.0)

See original GitHub issue

Current behavior

Downloaded or opened in the new tab csv, tsv or txt file contains a very long markup code before the actual content of the file, for example

<head> <script type='text/javascript'> document.domain = 'mydomain.us'; const cypressConfig = { modifyObstructiveThirdPartyCode: false, modifyObstructiveCode: true }; !function(a){var o={};function e(i){if(o[i])return o......(178000 more characters).....,0:function(a,o,e){a.exports=e("./injection/cross-origin.js")}}); </script> </head>

column_name	table_name	value_type	encoding_id	ordaunits	notes
ins_index	deatch	11	0	1	A numerical index used to distinguish the cases where we have multiple death records for a participant.
date_of_death	death	51	0	4	Date of death
dsource	death	41	1970	2	The data source is either E/W for England & Wales or SCOT for Scotland.
eid	death	11	0	0	This identifier is the same encoded id used in the main dataset.
source	death	11	261	3	The particular data format in which this record was received.

Desired behavior

Downloaded file should not contain any <head><script></script><head> markup.

It should contain actual csv/tsv/txt content, for example:

column_name	table_name	value_type	encoding_id	orda	units	notes
ins_index	deatch	11	0	1		A numerical index used to distinguish the cases where we have multiple death records for a participant.
date_of_death	death	51	0	4		Date of death
dsource	death	41	1970	2		The data source is either E/W for England & Wales or SCOT for Scotland.
eid	death	11	0	0		This identifier is the same encoded id used in the main dataset.
source	death	11	261	3		The particular data format in which this record was received.

The issue started to happen after we updated Cypress from 10.8.0 to 10.9.0. Also occurs in Cypress 10.10.0

Test code to reproduce

cy.readFile("downloads/record_column.csv").then((text) => {
      cy.readFile("./fixtures/bencmarkFiles/record_column.csv").should("eq", text);
});

Sadly, the issue is not reproducible when we’re trying to download sample CSVs from here: https://www.sample-videos.com/download-sample-csv.php , it happens only on our product, which is closed to the public 😦
