Template tags possibly causing compatibility issues with other plugins

[ice9js]

Describe the bug

Note: looking at master this might not be an issue anymore but I figured it's worth noting anyway. Feel free to close if that's the case.

It seems template tags are a bit of a grey area in WordPress and other plugins could be using similar tags or remove them entirely. Hence it might not be the most reliable way to inject buttons/navigation into the lightbox.

As described in the issue on Nimble Builder Plugin, when the two are installed along each other Modula's navigation doesn't display at all.

To Reproduce

1. Make sure to have both Nimble Page Builder and Modula installed along each other.
2. Proceed to create a gallery with arrow navigation enabled.
3. When viewing the page and clicking on an image, the lightbox will appear but without any arrows or a close button making the page effectively stuck.

Expected behavior

The gallery should render as expected.

Proposed solution
Like I said, might not be a problem anymore although I also don't necessarily see a reason to use template tags over something like the class name to inject the appropriate UI, where the latter would seem to have been more reliable in this case.

Hope this helps!
