Fonts get smaller in Jira macros exported to PDF

Issue Summary

In certain instances, when exporting pages that have Jira macros to PDF, the fonts within the Jira fields will be very small, impacting on its view.

Steps to Reproduce

1. Create a Confluence page and insert the Jira issues macro to it.
2. While configuring the Jira issues macro, make sure to select Table under the Display Options part.
3. Select some fields like Description or custom fields that use text.
4. Publish the page and export it to PDF.

Expected Results

The fonts should match the results from the published version of the page. For example (tested on a personal instance):

JIT-AddingaJiraissuesmacro-BothproductshaveIPallowlistingenabled-041022-2038.pdf

Actual Results

The fonts get very small within the Jira macros. For example (tested on a personal instance):
