problem with certain tag attributes

[smithy545]

I've run across a problem where some of my tag attributes don't work properly. The error I get is

...
File "<string>", line 1
    pyjade.runtime.attrs(attrs=[('name', ("valuePurchased" value="0")])
SyntaxError: invalid syntax

Now the tag itself looks like this

input(type="range" name="valuePurchased" value="0")

Clearly there is something wrong with how the parser is parsing the attributes as it's including the entire value attribute within the name attribute's value (it also happens when I switched the order of the name and value attributes). Now I thought it could be another error somewhere else in my jade that's resulting in an error here, as I've had that before, so I deleted the whole template file so was just this one line and I still got the exact same error.

I have something like this:

If input is like input.form__input(type="tel" placeholder="+7 999 999-99-99" required)
Compilation fails with
jinja2.exceptions.TemplateSyntaxError: expected token ')', got 'required'

after moving required attr to the beginning, for example
input.form__input(type="tel" required placeholder="+7 999 999-99-99")
Compilation works

It's not okey when I have only one attr and it's a conflict one, for example data
li.tabs-section__content-item(data-number="1")
Compilation fails with
jinja2.exceptions.TemplateSyntaxError: expected token ')', got 'data'
