zip file of the first pages from Alkaline battery article rendered on two dates

A year or so ago the "Download as PDF" option worked very well with good
results. The current operation of this option is very bad. In some cases
such as the article Coffee, ([1] the PDF
of the article does not even include the two tables in the section

Caffeine content

The caffeine content of a cup of coffee varies depending mainly on the brewing
method, and also on the variety of seed.[2][172]

According to an article in the Journal of the American Dietetic Association,
coffee has the following caffeine content, depending on how it is

Serving size

Caffeine content

[the table omitted should be-------------------------------------------------]

Brewed 7 oz, 207 ml 80?135 mg

Drip 7 oz, 207 ml 115?175 mg

Espresso 1.5?2 oz, 45?60 ml 100 mg

[end omitted table-----------------------------------------------------------]

While the percent of caffeine content in coffee seeds themselves diminishes
with increased roast level, the opposite is true for coffee brewed from
different grinds and brewing methods using the same proportion of coffee to
water volume. The coffee sack (similar to the French press and other steeping
methods) extracts more caffeine from dark roasted seeds; the percolator and
espresso methods extract more caffeine from light roasted seeds.[4][174]

Light roast

Medium roast

Dark roast

[the table omitted should be-------------------------------------------------]

Coffee sack ? coarse grind 0.046 0.045 0.054

Percolator ? coarse grind 0.068 0.065 0.060

Espresso ? fine grind 0.069 0.062 0.061

As another example, I got the Alkaline battery article about a year ago and
saved it as "Alkaline battery (Wikipedia-20131120).pdf" and it has a size of
2,260 KB. When I get the same article today, and save it as "Alkaline battery
(Wikipedia-20141004).pdf" it has a size of 14,492 KB. I have attached the
first page of the two versions of this article for your comparison.
