Custom tags are not working for partials

[stackchain]

If you use custom tags like <% it works only for the template main file, all partials inside don't keep this configuration, the partials only work with the standard tag {{.

Template
{
my_hi_message: "hi",
my_hi_message_2: "yo"
}

File1.txt
<% my_hi_message %>
<%> my_partial_file.txt %>

My_Partial_File.txt
<% my_hi_message_2 %>

Output:
hi
<% my_hi_message_2 %>

---- If I keep the original tag {{ inside partials it works, it looks like subRender problem.
File1.txt
<% my_hi_message %>
<%> my_partial_file.txt %>

My_Partial_File.txt
{{ my_hi_message_2 }}

Output:
hi
yo
