flashtext | Rust implementation of flashtext algorithm | Search Engine library

I am writing to show a flash text to the user, I want it to disappear after 3 seconds. I have tried to use settimeout but there's no result, I can change the colour and other properties but not the display property.I am using bootstrap for the styling. This is my code:

I've spent quite sometime trying to figure this out. I understand there are multiple questions online and stackoverflow where this issue is resolved, I've tried to do exactly the same thing in my case however I seem to run into the issue where clearInterval does not work.

My code:

I'm trying to explode a column of a dataframe to get multiple rows. The column to explode it's called keywords, which are a list of emotions returned as keywords from the package FlashText. This means if a keyword is in the text column (column with sentences), then it will return that emotion or multiple emotions corresponding to that sentence

If I use an example dataframe created by me, this works perfectly with an expected output, however when applied to the dataframe explode it returns a random combination of rows.

I thought this unexpected results were because the dataframes have duplicate indexes, however, drop them gaves the same wrong result.

The KeywordProcessor used to extract keywords from FlashText is returning NaN at the end of the dataframe. The shape of the dataframe is (14.532.885, 6), where just one column (which contain sentences) is used to extract certain keywords.

The keywords extraction is correctly applied until the row 14.452.474. In other words, extraction is not applied to 80.411 final rows from the sentence column.
